    Introduction

    Tempotec is a veteran brand of audio products, whose catalog consists of several series:

    • Fantasy: (DA II Plus, DP, B-HP). They are stationary products, focused on large size headphones and energy demand.
    • Serenade: (iDSD, DA, PCI-E). They are products designed for use mainly with PCs, since they are external sound cards, even internal, with different functions each one of them.
    • Sonata: These are portable amplifiers and DACs,
    • Variations: (V1, V1A). This series is quite recent and consists of a player designed for connection to an amplifier or Bluetooth receiver system (V1) and a complete DAP with headphone output (V1-A).

    On this occasion, the product I'm going to analyze, the Tempotec Serenade iDSD, is a very complete DAC/AMP, which has many possibilities of connection and use.

    Among its features is the exclusive HiBy processor, capable of decoding DSD, APE, FLAC, WAV and MP3. It plays any DSD 64/128 format natively. You can also play high resolution music through the HiBy App from any IOS or Android device connected to it.

    The method used for the digital transmission of the signal through the USB port is asynchronous, in order to offer a more precise sound, a larger scene and a lot of details.

    The iDSD uses the AKM AK4490EQ DAC, the TPA6120A2 Ti amplifier and the LME 49720NA operational amplifier. In addition, this OpAmp can be replaced by another, as it is mounted in a socket that allows easy replacement.

    Packaging

    The iDSD comes in a large cardboard box, which protects its packaging. Its dimensions are 260x213x72mm. This box is not generic, despite being the typical brown box, but contains the model name and description. In its interior already appears the packing "of exhibition". The upper part is decorated with the name of the series and the logo of the brand, as well as a pair of QR codes.

    It opens like a chest and inside, the first thing you see is a sheet of white protective foam. Underneath it is the iDSD, embedded in a foam mold, also white. On top of it, there is a zip bag with the instruction booklet and the warranty. To the right of the protection mould, there is an elongated white box. Inside is the power supply, with European plug (a detail by the brand), a USB cable with gold-plated connectors (another great detail) and two supports to measure, to place the iDSD standing.

    The dimensions of the iDSD, excluding the potentiometer and connectors, are: 122x128x32 mm

    The packaging is fully adequate and the product is suitably protected. The content is the minimum required for the operation of the system. Nothing to object to in this respect.

    Construction and Design

    The iDSD has a striking, eye-catching design: a silver-plated aluminium housing, rounded at the edges, provides this effect. It has a black front and back. On the left front, there are two small silver buttons, one to select the USB input port (USB or Portable), and another to select the output (headphones, line or coaxial). In the middle is the potentiometer, a black plastic cylinder, which lacks any mark or notch, which indicates the level. On the right side, slightly downwards, is the 3.5mm headphone output. Finally, next to the letters iDSD, there is the 6.3mm headphone output.

    At the rear, at both ends, two Philips screws can be seen. On the left side is the power switch. Next to it, on your right, is the power input. Following the order, are the two RCA outputs, conveniently gold plated. Then there is the coaxial output, also gold plated. Finally there are the USB inputs, first type B, for the connection with the PC, then the portable USB input, type A, vertically, for the connection of Smartphones IOS, Android, tablets, etc.

    After unscrewing the two screws and removing the potentiometer nut, the iDSD can be disassembled to check its interior. And it is worth seeing, apart from the HiBy chip, the AKM AK4490EQ DAC, the TPA6120A2 Ti amplifier and the LME 49720NA operational amplifier, the use of Nichicon Gold series capacitors can be proudly observed, as well as the high level of the other components used.

    The iDSD can be placed horizontally, as well as vertically, on the translucent plastic brackets that come with it. The outer casing acts as a radiator and, even though it is not very hot compared to other DACs I have, if the support surface is susceptible to heat damage, I suggest using the bases for its vertical arrangement. And, although these bases seem very simple, the vertical stability with these pieces is surprising.

    In my opinion, both the design and the construction are excellent for their price. The only thing I miss is a small slot in the potentiometer knob to determine the volume level. This way you could avoid some damage to the IEMS after turning on the iDSD, because it is at a very high volume.

    Connectivity

    Connectivity is multiple, but simple. As inputs there is a USB port type B, for connection to PC, and a USB port type A, for connection to mobile devices. Mobile devices can also be connected via USB B, so they can even be charged.

    For outputs you can use the front headphone sockets, the line RCA output or the digital coaxial output.

    Both inputs and outputs are selectable via dedicated front buttons.

    The main use that I have used for this review has been connected to my PC, through the USB-B port, using Foobar2000 as playback software. The driver used is the original one, in its version 3.26.0.

    The installation of the driver is not complicated, I only recommend that you install the driver first and then connect the iDSD to the USB of the PC.

    Sound

    The iDSD has a totally flat frequency response, but it also has an output impedance of approximately 10 Ω. As you can see, I have made some measurements on IEMs that I have, without reaching a specific conclusion, which allows to extract a fixed rule, on the incidence of this impedance on the IEMs tested. Compared to my reference DAC, the Burson Audio Playmate, the FR have hardly any differences in the low or medium part. Sometimes, the upper end seems more mitigated with the iDSD. But I must advance that my measurement method is not very accurate above 15kHz. The biggest difference can be seen in the Rose Mini2 MKII 2.0, where you can see a higher gain, starting above 200Hz.

    As I have always maintained, a high output impedance is responsible for a modification in the frequency response of the connected IEMs. But, on this occasion, the incidence seems small enough to determine that it is negative. In this sense, it is also very important that the components close to the headphone output are very well chosen, so that they do not behave like filters that modify, in a fixed way, the frequency response of the connected headphones. On this occasion, this is not so, as you can see in the graphs above. This means that the electrical circuit has been very well thought out and tested, to offer maximum sound quality, without negatively interfering with the frequency response of each connected headphone.

    The first impression I had after trying the iDSD, is a real sense of power and energy, a very vivid sound, strong, with punch, very funny and forceful. As I say, the sound shakes from the first listening, causing me a clear smile, moved by the aggressive character of the iDSD. But let no one understand aggressive, a sound out of control or hurtful. With this adjective I want to highlight the strength and vitality of the iDSD and move away from a calm or relaxed tone. The iDSD has been created to provoke great emotions. And that's not only demonstrated in the lower zone, but it's also perceived from above, because it offers a dynamic and marked sound, but with a treble that's a little harder than delicate. The mids are also very expressive, following the character of the iDSD, they have a clear tendency to offer a sensation of direct and big sound, with a lot of personality, marked details and good level of detail.

    At scene level the level is remarkable, as is its separation, but it is not the strong point of the whole. It is clear that, in this sense, it is possible to change the OpAmp for others, with the intention of improving in this sense. For this occasion, I have used Burson Audio's OpAmp V5i, obtaining a greater clarity and gaining more scene, without losing the vigorous character of its sound.

    But on this occasion, to better understand the sound of the iDSD, I have based myself on comparisons with my reference system, the Burson Audio Playmate, and then with another DAC of similar price, although smaller and more portable, the Sabaj DA3.

    Comparisons

    Burson Audio Playmate (399$)


    The Playmate is worth more than three times, but we all know that the sound is not quantified in the same way as the price. By this I mean that, although the Playmate sound is a reference, the iDSD doesn't sound three times worse, that's clear.

    In terms of construction, size, volume control and control panel, that's where part of the price difference lies. The volume control, in the Playmate, is digital and extremely precise, with two gain modes. It has the possibility of applying filters and a microphone input. In something that the iDSD beats the Playmate, it is in the two audio outputs (3.5mm and 6.3mm). When you open the inside of both, although both are very well organized and use excellent components, the Playmate stands out clearly, the use of transistors in class A offers a hard difference to overcome. In addition, the Playmate has 4 OpAmps versus 1 from the iDSD, as they are used in different phases of amplification. In the end, all this doesn't just translate to sound, but also to a greater amount of power offered by the Playmate.

    The Burson offers a more neutral, wider and softer sound, somewhat removed from the energy sensation of the iDSD. This is something that is already demonstrated in the lower zone. The strength of the iDSD in the mid-low surpasses the Playmate feel in this sense. By contrast, the iDSD doesn't have such a deep extension, nor the detailed, smooth texture of the Burson. This tonic is repeated in both mid and treble.

    The mid zone of the iDSD is perceived to be somewhat more congested than that offered by the Playmate, where the greater sound expansion offers greater naturalness and three-dimensionality in this zone. In this way, the elements are positioned with more space, being able to appreciate with more tranquillity, even closeness. In the treble, the iDSD is somewhat harder and more tense, where the Playmate is executed in a sweeter and more defined way, boasting an airy and separate sound, both in the midrange and in the upper zone.

    But one of the great differences between the two is in the amplitude of the sound: the Playmate here stands out for its analytical ability and higher resolution, not that this means that its sound is analytical, but more balanced. Its higher level of detail and nuances, counteracts the energy of the iDSD, offering a wider width, a larger stage, versus the forcefulness and sound in the foreground of the iDSD.

    If you had to sum up the sound of both in one word, the iDSD would be fun and the Playmate refined.

    In terms of size, the Playmate is larger and designed to be positioned horizontally. Meanwhile, the iDSD is narrower, lower and deeper. In addition, it can be used horizontally or vertically, thanks to its supports. It also weighs less. The disadvantage of the iDSD is that in both positions, due to its low weight, it moves when the headphone jack is inserted. The Playmate, thanks to its weight and non-slip feet, offer a better experience in this regard.

    The Burson's class A performance makes it much hotter than the iDSD, even if it's just moving IEMs, i.e. working at low power.

    The iDSD potentiometer is analog and very sensitive to IEMs, that feeling of power is also determined by the sensitivity of the potentiometer: for IEMs, as little movement, the volume is raised a lot, is something that must be taken into account. The Playmate, apart from the fact that the volume is digital and goes by steps, which are shown on its display, has a much more gradual advance, in addition to having a gain selector, to even improve the sensitivity of the volume.

    Serenade 33.png Serenade 34.png Serenade 35.png Serenade 36.png Serenade 37.png Serenade 38.png

    Sabaj DA3 (105$)

    The DA3 is a small DAC, which uses two SABRE9018Q2C and has some big specifications. It is characterized by a low noise level, very low distortion, very good linearity and low output impedance (around 2 Ω). It has a balanced output and a small informative screen. All this in a very reduced size. In addition, it is designed for use as a DAC connected to the PC, as its bottom has a rubber EVA band to prevent slippage and improve grip. Without entering into any comparison, the sound is something particular, and is not exactly characterized by being sweet, but quite the opposite. On this occasion, it can be said that the sound of the DA3 is more aggressive, harder, less harmonious, less sweet and delicate, somewhat excessive, but very concrete, with a more sharp definition. And this is something that you can see with the passing of time. Depending on the IEMs used, the sound can be tiring, as it is not very friendly with delicate or analytical IEMs, because they enhance that sharp and harsh character it possesses. But with other more relaxed IEMs the sound is more pleasant.

    This fact contrasts strongly with the sound of the iDSD, despite its power, the sound is not fatiguing, and, after a quick change between both DACs, the iDSD transmits much sweeter and a delicacy, which is appreciated.

    In the lower zone both have a good representation, but the texture of the iDSD is softer and natural. This fact expands the bass in all senses, getting a more comfortable effect.

    In the mid zone, the abrupt look of the DA3 remains, offering a clean sound, but less natural, comparatively speaking. Meanwhile, the iDSD stands out with its powerful, but velvety, sweeter and more harmonious sound. Both nuances can be observed taking the voices as a reference: in the DA3 they are perceived more tense, while the iDSD, even turning up the volume more, are kept at bay, always within the harmony.

    In the upper zone is where the DA3 is shot: this part gives that more strident nuance that characterizes it. While iDSD is more polarized in the lower zone, offering great width and depth, but without underestimating the treble, nor much less, the details. That's the big difference: while the DA3 seems to offer a cooler, sharper sound, the level of detail and nuance is noticeably higher on the iDSD, providing an open, rich, separate, clean and deep sound. And the scene benefits from these aspects: the depth of the iDSD generates a larger and wider image, with greater height and length, more three-dimensional. The DA3's sharper, more concrete sound narrows, without expanding as naturally as iDSD does.

    The great advantage of the DA3 is its size, it can become a perfect travel ally, with a more than decent sound quality. It also has an independent balanced output, which makes it even more attractive. But if you're looking for something more stationary, more powerful and more versatile, for little more, the iDSD provides a clearly better listening experience.

    Conclusion

    Without a doubt, the iDSD offers an excellent sound for its price. I don't think there are many DACs in this range that can give me as much satisfaction as this magnificent and versatile Tempotec. And that's something you feel from the first minute, no later comparison is necessary. Rarely am I so categorical in this sense: if someone asks me for a DAC around 125$, it is clear that I would recommend the Tempotec Serenade iDSD, as option number 1.

    The iDSD has a great sound, based on a strong character, powerful, dynamic and forceful, very fun, but without losing control or sweetness. In addition, it offers two audio outputs, so you don't have to use adapters (and both are equal in sound and power), many options of use and connectivity, possibility of changing the OpAmp, a simple but very effective construction, using very high quality components, wisely conjugated, to maximize the final result. A luxury that is difficult to beat.

    Tempotec Serenade iDSD — powerful desk DAC&AMP
    Written by IryxBRO
    Published Dec 7, 2018
    4.5/5,
    Pros - great sound, various usage scenarios, handy on the desk, can handle different headphones, neat soldering
    Cons - volume potentiometer could be a bit better
    Another interesting invention for us — TEMPOTEC Corporation that specializes on developing and manufacturing PC audio cards and recently focusing and shifting to home audio appliance field. Despite the fact that TEMPOTEC has more than two decades of history, we don’t see its products on the shelves of local stores quite often. Their supply to different parts of the world is definitely present but we haven’t found the overwhelming amount of information or owner feedback about Tempotec devices.

    Current Tempotec family has several device lineups: Serenade, Fantasia and Sonata. Sonata is the most portable family of DAC&AMP devices with inbuilt batteries and small dimensions. Fantasia is another extreme — a whole system for the most demanding full-size headphones. Finally, Serenade series includes DAC&AMPs as standalone desktop products with no batteries inside. Moreover, there are PCI-e cards sharing some family characteristics for those who would like to integrate it to their PC-based sound or gaming workstation.

    After getting more familiar with current Tempotec series of products, we would try to correct our own mistake of not following weighty industry names by examining and reviewing Tempotec relatively new device — Serenade iDSD standalone DAC&AMP which is aimed to upgrade any digital audio source to HiRes audio standards.

    Box contents:

    [​IMG]
    [​IMG]

    Serenade iDSD comes in large carton box filled with soft foam rubber as a retainer and includes just a few additional accessories:
    1. Serenade iDSD
    2. DC, 5V switching power supply
    3. USB type B -> USB type A cable
    4. Plastic stands x2
    5. Chineese user manual
    [​IMG]

    Not very rich box contents but enough to cover the main instance of connecting to PC or Mac.

    Additionally, you might need USB type B -> microUSB/USB type-C adaptor to connect to Android OS smartphones or USB type A -> microUSB/USB type-C to connect to iOS or Android smartphones in private mode if the first option failed.

    Design and build quality:

    Serenade iDSD case (acting as chassis) is made of thick alluminum-alloy with plastic front and metal back parts. Front part consists of two input|output selection buttons and corresponding blue LEDs, analog volume pot and two headphone outputs: 3.5mm and 6.3mm.

    [​IMG]

    Back panel is occupied by power ON/OFF switch, RCA L+R lineout, Digital coaxial, power jack input, USB type A and USB type B inputs.

    [​IMG]

    Plastic stands do a great job of holding the device in vertical position allowing it to dissipate heat effectively.

    Overall build quality is on a very good level. Nothing rattles inside, all elements are neat and all labels are accurate enough to create first positive impression. Almost half of a kilo weight is reasonable concerning thick alluminum chassis.

    Hardware part:

    This is the most peculiar part that allows us to belive that Serenade iDSD is a very good bargain:
    • it is based on mighty Asahi Kasei AK4490EQ premium line DAC which can also be found in DACs of such brands as Denon, Teac, Marantz, Onkyo, Esoteric and so on…
    • it is capable of up to 32bit/192kHz
    • it uses Texas Instruments TPA6120A2 high fidelity stereo headphones amplifier + Ti LME49720 high fidelity OPAmp that would drive 600Ohms loads at 75mW.
    • it utilizes Nichicon Line Gold series capacitors
    • its CPU is specially designed for HiRes audio performance by HiBy
    • etc…
    and all of this comes in a price of less than $140!!!

    [​IMG]

    Moreover, although it is not stated in the description, OPAmp is not soldered and easily swappable. This also adds some value to the device for those who would like to conduct further experiments to the resulting sound.

    [​IMG]

    BTW, tearing down Serenade iDSD is very easy — it is a matter of unscrewing just 2 screws on the back panel, removing volume pot (pulling it off) and unscrewing large nut that holds volume potentiometer at place.

    [​IMG]

    Soldering and the whole circuit board looks to be assembled very carefully. There are no signs of neglect soldering or cheap mass production processes.

    Device operation:

    There are two usage scenarios in terms of inputs and other three in terms of outputs.

    First of all, we have tried to connect is to Win10 OS based PC. USB B -> USB A cable is included and the only trick to make it work is to locate the appropriate drivers. In order for Serenade to run with PC you would have to use front buttons and set left one (input) at «U» (which means USB) and right one (output) to either of three options which are: «C» (coaxial), «L» (lineout), «H» (headphones).

    [​IMG]

    Windows 10 would recognize this device as Tempotec external DAC and allow to direct audio stream by the means of Wasapi (from Foobar2000) with almost non-existing audio lag. If you prefer ASIO over Wasapi, you’d have to download and install this driver.

    Other option is to use Serenade iDSD with a smartphone. Our testing device is Xiaomi Redmi Note 4 which works perfectly using USB A -> microUSB cable and using input «P» (private mode input) on the front panel. Output options are limited to lineout and headphones in this case. Coaxial output would only work while «U» input is selected.

    [​IMG]

    And the last option which wouldn’t be used often is digital transport — connecting PC to Serenade iDSD and using digital output (coaxial) to pass the stream further…

    [​IMG]

    Concerning the fact that Serenade iDSD is not intended to be carried around and it doesn’t have autonomous power source — our main usage scenario would be connecting it to PC and listening music through headphones, active speakers or passive speakers with power amplifier and iDSD playing pre-amplifier role. All options are perfectly usable and moreover, there is no need to disconnect either of the output devices thanks to output selection button.

    One little negative point — unfortunately, volume pot would not utilize its full mechanical travel. Max volume is reached at about 85-90% of travel and there is no further influence.

    [​IMG]

    Please note that Serenade iDSD heats up to ~38-42°C while operating and it is better to keep it standing vertically to avoid excessive heating or damage to desk surface.

    Sound quality:

    As always, we would try to compare instead of writing only about Serenade iDSD sound quality. The essence shows up only in comparison… Our comparison would be done to Hidizs Sonata DH1000 which is portable, battery-equipped DAC&AMP with the additional balanced output and which audio quality is respected by many owners who bought their units recently and comapred to other more expensive rivals. Sonata DH1000 is a real beast in terms of high fidelity audio due to enhanced and complicated hardware architecture and despite a compact formfactor. In order to get a closer look — here is a link to out review of Hidizs Sonata DH1000. We would also be using our favorite pair of full-sized monitor headphones — Audio-Technica ATH-M50 (38Ohms), plus a good pair of high quality IEMs — Dawnwood ST08 (18Ohms)……….

    [​IMG]

    Maaaaaannn!!! Tempotec Serenade iDSD sounds very good. It doesn’t matter whether the direct comparison is done to a mighty Sonata DH1000 or it was a separate session of audio listening experience — Serenade iDSD has very matured and engaging sound.

    First what we’ve noticed was a bit of emphasis on lows that is a pefect choice for IEMs that always trail behind full-sized ATH-M50 in this aspect. Don’t get us wrong — lows are not overpowered or overemphasized — they are just at the right spot. Sonata DH1000 acts more gentle in this respect and would be a better match for ATH-M50 that tend more to low-end.

    [​IMG]

    Midbass section is very powerful and punchy which is not a surprise for such output ability of amplifier section. 300mW at 32Ohms results in very good driving potential and really makes you feel each drum hit that is so energetic as if you are standing next to it. Sonata DH1000 does the same but its output power is two times less which results in lower driving ability for loads higher than 150Ohms.

    Highs do not disappoint either — very good resolution of smallest details, no harsh sounds and no hissess. Top is in good balance with the overall sound picture of this device. Seems to be on par with Sonata DH1000 with a bit of advantage in transparency in DH1000 top-end.

    Sound stage is wide with good horizintal and vertical instrument separation and vocals standing a bit in front of the entire scene. The most interesting fact is that despite using a single DAC + amp Serenade iDSD sound stage is just a fraction less to Sonata DH1000 which utilizes double DAC&Amp architercure to get the most channel separation…

    [​IMG]

    Finally, after spending countless hours with both devices — we came to the conclusion that we can hardly find significant difference in their audio performance apart from different low-end signature and some more intimacy and gentleness in Sonata DH1000 sound. Both have excellent audio quality and both should be considered as a great bargain. The only case when their differences really come into play is when we start to think about their additional capabilities and usage scenarios… In this respect — they are very different indeed.

    Let’s do a final comparison in terms of base and additional features:

    Tempotec Serenade iDSD:

    Pros:
    • High power output (300mW @ 32Ohms, up to 75mW @ 600Ohms)
    • 32bit/192kHz
    • Swappable OPAmp
    • Lineout
    • Enhanced low-end
    • Excellent sound quality, especially with higher loads or IEMs with no emphasis on lows
    • Price
    Cons:
    • Desktop usage only
    • Requires additional power supply
    • No balanced headphone output

    Hidizs Sonata DH1000:

    Pros:
    • 3.5mm unbalanced + 2.5mm balanced output
    • double (balanced) DAC&AMP design
    • portable, has autonomous power
    • excellent sound quality with any headphones
    Cons:
    • Price is higher
    • Less powerful output (150mW @ 32Ohms balanced, 120mW @ 32Ohms unbalanced)
    • No dedicated linout
    Therefore, if the main intention is to drive headphones with up to 150Ohms on the go — Hidizs Sonata DH1000 would be a better choice. But in case if there is no need to carry such device in your pocket or if your headphones require more powerful output — Tempotec Serenade iDSD would be a perfect match.

    Conclusion:

    [​IMG]

    As a matter of fact, we are really impressed with Tempotec Serenade iDSD performance. This is the first device from Tempotec we’ve ever held in our hands and it exceeded our best expectations. Since the time we’ve reviewed Sonata DH1000, we thought that it would be a long wait for another device to take over or at least to stand in line… but the day has come — Serenade iDSD could be considered as the closest rival in terms of audio quality with just a fraction of simplicity in overall sound signature and at a way less cost. Though, it cannot be considered as 100% substitution due to almost completely different possible usage scenarios… Therefore, you get a choice of two perfect options and for a different budget… isn’t that’s great?

    Tempotec Serenade iDSD is currently available through Hidizs official store. Additional discount can be found on my website

    HIDIZS Tempotec Serenade iDSD Review - Desk Friend

    [​IMG]



    Introduction

    HIDIZS Tempotec Serenade is a new DAC/AMP from HIDIZS made for desktop usage. It is an entry-level unit, priced very accessible, at just 140 USD, making it one of the least expensive Desktop DAC/AMP units we reviewed so far. It has a lot of competition, even from the portable AMP department, and it will have to do quite a lot to stay alive at this point, and today we're going to find out whether it stays afloat or sinks.

    HIDIZS is a friendly company, but they have slightly poor communication in general, and you need to be patient to get answers from them. They generally do solve issues where they arise, although I generally advise to purchase from a seller when possible, as HIDIZS's own PR and Customer Relations department may be a little underdeveloped for their always growing size, and you'll get a quicker service by ordering their products from a seller, and you're also helping them by taking some heat off their back. There are many sellers with a golden overall support and service, and working with them means you get that service for your HIDIZS Product.

    It should be noted that I have absolutely no affiliation with HIDIZS, I am not receiving any incentive for this review or to sweeten things out. This review is not sponsored nor has been paid for by HIDIZS or anyone else. I'd like to thank HIDIZS for providing the sample for the review. The sample was provided along with HIDIZS's request for an honest and unbiased review. This review reflects my personal experience with HIDIZS Tempotec Serenade. Every opinion expressed is mine and I stand by it, the purpose of this review is to help those interested in HIDIZS Tempotec Serenade find their next music companion.

    Packaging

    Starting with the package, we must note that Tempotec Serenade isn't necessarily made by HIDIZS, but by a third company named Tempotec, HIDIZS applying some of their own branding, and while this information is not confirmed officially, also changing the sound to some degree. In a prior conversation with someone holding insight, they said that the version sold by HIDIZS is slightly different from the version sold by tempotec, but regardless, they should be close enough for this review to hold true for both.

    The package is of high-quality, and for the price paid, you get quite the nice overall exposition.

    There is a larger white package where you can find the Serenade comfy sitting in a soft foam, next to a little box which includes a few essentials. Among those, there are two plastic feet which can help you sit the unit straight (on the side), instead of lying flat, a power brick, which ends in a universal connector, with adapters to worldwide sockets included in the package.

    There's not much else in the package, and not much else to talk about, really, this still is more than what more expensive products come with, and I can't complain much, it includes all the essentials you need to use it, and the package quality and content is great for a product at this price, only very few products in this price range coming with more extra.



    What to look in when purchasing a high-end DAC/AMP

    Technical Specifications

    [​IMG]



    Build Quality/Aesthetics/UI/Firmware

    The build quality is excellent, and while this isn't something necessarily typical of all HIDIZS Products, if we're talking about older products (AP200), the new ones are really well built (AP80, Serenade, HD Sonata DAC). The device is mostly made of a metallic outer shell, and a face, with a volume knob, two buttons, and two headphone jacks. At the back, you can find the Power Input, the Line Output, a Digital Coaxial Output, and two USB inputs.

    [​IMG]

    [​IMG]

    The volume wheel is a fully analogue potentiometer, so it does have channel imbalance at the beginning, or lower volumes, but not a lot of it. The volume wheel has a nice amount of dampening to it, so you can finely adjust the volume. There are two buttons on the front, each of which is used to select the input and the output.

    There are two inputs, two USB ports, one for PC / MAC , and one for OTG connections. Also, you can chose to use a Line-Out output through the RCA connectors, or a digital output through the Coax connector.

    There are two 3.5mm and 6.3mm Single Ended Jack connectors at the front.

    The Serenade cannot be powered via USB, and it requires its own power source, so you need to have it connected to the wall. This is kind of disappointing, and this means you can't use on-the-go at all, opposed to similar devices like iDSD Black Label from iFi, which although large, can be powered from USB, and even from its own battery.

    The other little complaint I have, is that its Coaux digital output is a bit pointless, since you're most probably not going to have a Wall Powered digital transport, and if you are, you're probably going to invest quite a bit more in it, as you'll most probably want a few other features with it as well. This being said, it is always good to have something rather than not have it at all.

    The DAC HIDIZS and Tempotec selected for the Serenade is AKM 4990, which is known to be a pretty smooth-sounding DAC, but it is fair to mention that it is one of the better and more versatile DACs our there, being able to decode virtually anything you throw at it, including DSD files (up to DSD 128)


    To be fair to it, the device is actually named Tempotec Serenade iDSD, so it is natural that it can decode DSD files.

    The glossy finish on the front and the back is nice, slightly fingerprint-prone, but nothing too serious.

    [​IMG]

    The power rating for The Serenade is about 75mW / 600 OHMs, judging by the info quoted in the book, and with a power rating of 300mW / 32 OHM, confirmed by HIDIZS. This means that iDSD Serenade has a lot of power for a device in this price area, making it one of the most capable devices at this price, if not the most capable in terms of driving power, for 140 USD. The manual also states another really amazing spec for it, a Noise of 0.00014%, making iDSD truly outstanding, of this rating is achieved in real life performance.

    One little complaint comes to mind, which is that the plastic feet have no connection with the unit, they are basically just that, plastic feet, and they are quite slippery, so using the unit in a vertical position, while possible, is not ideal.

    All in all, Serenade iDSD is a really solid device, and it can withstand falling off a desk without breaking, it looks sleek and friendly while on a desk, and it does a good job at what it's intended to do. It has all the basic connections you could desire, and it even features some extra connections, and for the price asked, it is a pretty well thought device, technically.



    Sound Quality

    Now, the signature of Serenade iDSD is quite unique and specific, it has a certain emphasis on the low end, being warmer, with a slightly enhanced, and slower sub-bass, it has a more forward midrange that sounds energetic, and the top end has a slightly enhanced sparkle, but its presence is slightly reduced, compared to the midrange.

    The bass is one of the slower types of bass, not overly quick, and slower than what I'd consider natural, it is slightly enhanced, and it is rather large in size. This makes up for a punchy and impressive presentation. Finer nuances are presented fairly well for the 140 USD iDSD Serenade costs, and it is able to deal a great amount of "blow", even with Headphones that really require this kind of Power, like Beyerdynamic Amiron, HIFIMAN Sundara, and HIFIMAN HE-400i.

    [​IMG]

    The midrange has a fairly natural overall tonality, without a strong emphasis on textures, most of the midrange being natural to slow, the textures being within what I'd consider natural. The tonality is natural to neutral, and despite the enhanced low end, the midrange stays fairly faithful to the recording, and isn't colored by the bass.

    The treble of the Tempotec Serenade is fairly smooth in my experience, and it isn't a DAC/AMP you'd typically pair with a smooth headphone or IEM, as it would sound quite a bit too smooth. It isn't the presence that is smooth, and the treble is present enough to balance out the slightly forward midrange, and the slightly forward bass, but the texture of the treble is so smooth in general, that you couldn't get it to sound grainy with any single IEM or Headphone. This makes it a great DAC/AMP for those who are sensitive to Treble Grain, but it also makes it a bit too smooth for Metal and certain Electronic Music.

    The overall dynamic range, and dynamics are great to excellent, quite outstanding for a DAC/AMP at this price range, and it really makes a statement on what can be achieved by staying desktop, and not making it portable. Especially with harder to drive headphones, like Beyerdynamic Amiron, you can hear how much the dynamic range improves compared to a less powerful DAC/AMP. The overall control it has over headphones is also fairly solid, and it is able to impose a serious authority over headphones, making it a DAC/AMP not to be joked with.


    It should be noted, that to keep the noise levels low, Tempotec Serenade has a really high output impedance, of about 10 OHM, and it really requires something like iFi iEMatch to even out this difference. The one linked above is a 2.5mm balanced iEMatch, but the 3.5mm balanced unit does the same thing. This high output impedance means that it will present some hiss with hiss sensitive IEMs, and with IEMs that are lower than 30 OHM of impedance, it will have a little too little bottom end. With its power rating that high, this is an acceptable sacrifice, but you should keep it in mind, if you're planning on using it mainly with IEMs. With 32 OHM and higher impedance IEMs and Headphones, there's no issue, and it sounds as it should.



    Soundstage

    The Soundstage of Serenade iDSD is a more intimate one, and since the midrange is slightly forward, this is to be expected. This soundstage has a good amount of depth though, and the instrument layering is fairly good, at least for this price range.

    The instrument separation is natural, instruments aren't defined and cut separately, like they'd be by a higher-end source, but they aren't jumbled together either, so you get a fairly good sensation of what note each instrument is playing.


    The stereo separation and overall imaging is also fairly solid, and it does a fairly good job for a 140USD device. Of course, something more expensive, like the Burson Play Basic does a better job, but it is also double the price of Serenade iDSD, making it more of a comparison of "what you get for double the price", not necessarily a direct competitor.



    Desktop Usage

    HIDIZS Tempotec Serenade iDSD is really made to be a desktop-only device. It isn't made to be portable, and even calling it transportable is a bit of a stretch, since you require it requires its own power adapter, and its own cables, so you really need to carry a larger package to make use of it. In this sense, it is about as transportable as Burson Play is.

    Now, the desktop usage is pretty much excellent. The driver support is very solid and I couldn't encounter a single disconnect while using it with my computer, and I tested it with multiple computers and laptops, and it worked flawlessly with all of them.

    [​IMG]

    It comes with those feet to sit vertically, making it a nifty-looking device on your desk, or it can be sat horizontally, acquiring a more elegant overall aspect.

    There is no noise inherited from smartphones or Wifi, even if it is placed right next to the wifi antenna, which is great, as most desktop users may place it rather close to an antenna, and the cables it comes with are black in color, so you can do some quick and easy cable management to keep your desktop tidy. Also, the unit is fairly heavy in person, so it doesn't slide on your desk if you pull a little on the cables.

    The volume wheel is easily accessible, as are all the controls you could require with it, so if you made the cable connections right before, you'll never have to touch it again.


    For its intended usage, the only real complaint I have is that you really need to apply something to the plastic legs to give it a better vertical position stability, but otherwise, it is a very stable and good desktop device.



    Comparisons

    The main enemies of Tempotec Serenade iDSD will be iFi Nano BL (200 USD), HIDIZS DH1000 (300USD), and Burson Play (300 USD). The main reason it is being compared to more expensive devices is that they are mostly portable, and it should be able to overcome those to justify its price and design. It can easily overcome something like the Audirect Beam, but that one has roughly the same size as a USB cable, and can sound really amazing while staying that portable, making it a really uneven enemy for Tempotect Serenade iDSD in terms of design, price and intended usage scenario.

    [​IMG]

    HIDIZS Tempotec Serenade iDSD vs iFi iDSD Nano BL - Now, iNano BL is not exactly an enemy fit for Tempotec Serenade in terms of design, as iNano is actually an ultra-portable DAC/AMP from iFi, made to be both affordable and portable, while the Serenade is pretty much one of the larger and more fixed Desktop DAC/AMPs you don't generally take with you while on a trip. This being said, iNano BL is already more than 25% more expensive than HIDIZS Serenade, but you may still find yourself in a position to pick between them. The differences in terms of build quality and features aren't quite that interesting, as both are really well built, and both have an industrial edge to their aesthetics, but the differences in sound are the ones that will be driving your choice. For the overall tuning and signature, Tempotec Serenade is a more energetic overall device, with a more forward sound, it sounds more digital, with a bit of glare, and it is more tuned to work with things like aggressive music and electronic music, while iNano BL is made to work best with a larger variety of music, including Jazz and Classical. One could say that both are smooth in the treble, but iNano BL is also smooth and organic in the midrange, while HIDIZS Serenade is more forward, and has a more revealing approach. The bass is similar between the two, both are slightly warm, although the bass is slower and bigger in amount on The Serenade, and tighter on iNano BL. In terms of driving power, it is a pretty clear win for Tempotec Serenade, as it can even drive the HIFIMAN HE-400i really nicely, while iNano BL is best at driving IEMs. If you need a portable device, mainly to use with IEMs, and if you like a smoother, more laid-back sound that works well with everything, then iNano BL should be your weapon of choice, but if you want a Desktop unit, don't need the portability, if you have a lot of gear that is hard to drive, and if you prefer a more forward sound, then Tempotec Serenade should be up in your list, especially with that sweet price tag of just 140 USD it sports.

    HIDIZS Tempotec Serenade iDSD vs HIDIZS DH1000 - This is a good comparison, because both of those are HIDIZS products, and there's a good chance you are considering which one to get. DH1000 is considerably more expensive than the Serenade, priced at 300 USD, so over double the price of the Serenade. This being said, DH1000 has started to go on sale for almost the same price as the Serenade, and it is also available for a similar price as a product under the Tempotec branding. To get things started, DH1000 is a more stylish device, and where the Sonata looked good, DH1000 looks pretty darn amazing. DH1000 has a Balanced output in the form of a 2.5mm jack, so if you have balanced cables, DH1000 is the only of the two that sports it. DH1000 is really portable, you can simply pick it up and carry it around, stack to a smartphone, and it looks well stacked with anything, with its deep piano black color and glossy finish, and it can be powered without a very specific power adapter being chargeable from any USB socket, where HIDIZS Serenade iDSD is a Desktop unit, that requires its power adapter to work. In terms of sound, DH1000's sonic signature is leaner, warmer, smoother, and has a less present treble than the Serenade. This makes the Serenade feel like it has a bit of a glare all over, i feels more aggressive, has a bigger bass, and sounds more uplifting in general. DH1000's soundstage is quite a bit smaller in general when compared to the Serenade, which is both wider and deeper. Now, if you're looking for a DAC/AMP for your portables, then DH1000 will surely satisfy for the same price as The Serenade, and you can even share your music with your loved one during a bus trip, if you have a headphone with 2.5mm connector, and she has a typical 3.5mm SE connector. Think about the romance, just watching the falling snow outside, listening together to her favorite songs... On the other hand, if you want a desktop unit, which can drive your full-sized headphones, and if you don't want a smooth or laid back sound, then Tempotec Serenade makes a very compelling offer, being one of the few entry-level devices that really impress, next to the likes of FiiO K3.

    HIDIZS Tempotec Serenade iDSD vs Burson Play - Now, here's an interesting one, what if you had 300 USD instead of 140 USD, and what if you still wanted to get a desktop unit? At this price point you're already in the midrange territory, and Burson Play is the first unit that comes to mind. Physically, both are built very well, but Burson Play doesn't have an analogue potentiometer, so there's no channel imbalance at low volumes. The overall device feels just as solid, if not more solid, but there's no 3.5mm headphone jack, instead Burson Play having a 6.3mm Headphone Jack, and a 3.5mm microphone input. Burson Play has more overall stability while it is sat on a table, given its shape and rubber feet, and it can also be integrated inside a desktop computer. On the downsides of Burson Play, it gets quite a bit hotter compared to The Serenade. Burson Play can be upgraded easily to better OP-AMPs, Burson offering some interesting choices up the ladder, but the operation is complicated and you need to be very careful and read the warnings before you start. The Sonic Signature is similar actually, both are pretty forward devices, with an energetic and uplifting sound, the main differences being in the bass, where Burson Play is more linear, and has a quicker bass, while Tempotec Serenade has a slower and larger overall bass. The midrange is fairly similar, and if anything, Burson Play comes through as more detailed, revealing more textures, with a more aggressive detail retrieval, although this may also be interpreted as a slightly more digital sound. The treble is more emphasized on Burson Play, which is able to sound sparkly and more airy, with a much wider soundstage. Burson Play can also play DSD up to 256, and it has more driving power than Tempotec Serenade, especially with lower impedance Headphones. Until now, it sounds like Burson Play is a total winner, but if you want to save some cash, and if you want to go for something leaner, more natural, more comfortable, then The Serenade should service you very well, being less expensive than just the OP-AMPs of Burson Play.



    Pairing

    HIDIZS Tempotec Serenade iDSD pairs quite well with high-impedance cans and IEMs, and anything that's basically above 32 OHM of impedance. It has a good control, a good dynamic range, and generally, it makes a pleasing overall experience.


    HIDIZS Tempotec Serenade iDSD + Beyerdynamic Amiron - Beyerdynamic Amiron is still a favorite of mine, as it is as comfortable as HD800, but has a more emotional sound, less mature, and more friendly. Compared to HD800, it also has a smoother midrange, and a more musical tuning. Tempotec Serenade is actually amazing at driving them, as it is one of the least expensive DAC/AMPs that is able to gain so much control over their sound, providing them with a better bass response (they are light and neutral on bass, so the more forward and larger bass on The Serenade actually works well with them), and with a less forward treble, and upper midrange, where Amiron was slightly spiky, giving them a more natural, more versatile and more balanced overall sound. It is pleasing to see such great results from an entry-level DAC/AMP, and I hope HIDIZS keeps up this kind of work with future products.

    HIDIZS Tempotec Serenade iDSD + Crosszone CZ-1 - Crosszone CZ-1 is a Headphone I'm going to review soon (very soon), which is made in one of my favorite countries, Japan. A truly Japanese Headphone from head to toe, this is one of the most comfortable headphones I've seen, in line with the amazing Amiron, and even better. CZ-1 is one of the most gentle headphones I've seen with such a great attention to detail and to fine nuance, that you'd be hard pressed to find something quite as gentle and as focused as they are. This also means that they quite neutral in the bass though, with a more enhanced top end, and with a really organic overall sound. In terms of pairing, the Tempotec Serenade + CZ1 pairing, although unbalanced by the high-end nature of CZ-1, and the entry-level nature of The Serenade, sounds quite magnifique. The neutral and linear bass is sweetened with some impact from the warmer Serenade, the top end is actually brought down a notch, by the smoother treble of the Serenade. The more forward and aggressive midrange of The Serenade is actually giving CZ-1 a bit more edge, the pairing still sounding quite organic and musical, and proving that you can drive a flagship with a more affordable source, and get great results.

    HIDIZS Tempotec Serenade iDSD + Sennheiser HD660S - This is an interesting pairing, as HD660S was a really amazing Headphone from Sennheiser I had the chance to review in the past. I was quite impressed with what they did, and for folks who could never pick between HD600 and HD650, HD660S was a really good answer. Some rumors are even saying that Sennheiser is discontinuing the HD600 and HD650 lines, in favor of the new HD660S, but I haven't been able to confirm that rumor with Sennheiser yet. In terms of pairing, HD660S is a Desktop headphone, with no jokes, very few portable sources would be able to power it properly, and those are from the high-end segment almost always. Now, iDSD Serenade is able to do that, and even more, by giving them good dynamics, a nice sense of depth, and a splendid detail (considering its 140USD Price Tag). The most interesting aspect is the control The Serenade has over HD660S, which is a fairly hard to tame headphone, and especially at high volumes, you can expect an enticing experience, for a really affordable price.



    Value and Conclusion

    With a company like HIDIZS behind a product, I tried to be a little careful when reviewing it, as I want you to know and understand as much as it is possible about the product. This isn't because HIDIZS is a bad company, but their communication isn't always the best, the main reason behind this being a combination of a language barrier, and them being overwhelmed by growth, and needing to grow their PR and Customer Relations departments. This being said, they are generally pleasing to work with, and while AP200 wasn't exactly the best device out there, their AP80, DH1000, and Tempotec Serenade and Sonata HD are all very solid and come with no issues.

    [​IMG]

    Speaking of the Serenade, starting with the package, you get everything you could need to use the Serenade, and with a few extras. The power brick is of a fairly good quality, and it didn't burn out, despite being used in my hometown, where the electricity isn't quite that stable, and the other cables are fairly sturdy and of a high quality as well.

    The build quality of the Serenade is excellent, as it is a one-piece metallic device, and it will take a serious beating, and still come for more. With a volume wheel in the front, two Headphone Output jacks, and one RCA Line Out connection at the back, and even a Digital Coax connection, you can get sound out of it in multiple ways, and all of them sing with the same talent.

    The design is both modern and elegant, you can combine it with any desktop style, from a full Mac, to the best gaming PC with water cooling and LED lights, everything working quite nicely, as long as you take the time to do a little bit of cable management, and as long as you apply something to the plastic legs to keep them from slipping away, if you plan on using Serenade in vertical position.


    The sound quality is quite good, especially for the price range, the most evident pluses being the really strong power output, the excellent control, excellent dynamics (all relative to the price point, of course), the slightly forward bass and midrange, slightly intimate soundstage, and the smooth overall texture presentation. Especially if you have a headphone or IEM with the impedance above 32 OHM, you can expect a level of detail not usually found in portables at this price range, and if you have something that's hard to drive, you'll really hear a good dynamic range, all while staying on a tight budget.

    [​IMG]

    If you're looking for a strong desktop DAC/AMP to drive your headphones, and if you like good dynamics, smooth textures, relaxing overall texture presentation, and if you like a slightly intimate soundstage, HIDIZS Tempotec Serenade iDSD surely makes a compelling choice and you should check it out, especially if your budget is quite low, and if you want some of the best power you can get for the money.
