The DX260 is a step up from the DX180 with better detail and larger stage. I have both and don't use my DX180 unless the DX260 needs a charge. The comments that the DX340 is not ideal from EDM/Trance are stopping me from buying one right now and saving $1800. If I can get one in classifieds one day cheaper I may do that. I hope Ibasso has a good amp section in the next tube amp card. I have a Cayin N3Ultra and not impressed which I plan on selling - my only non-iBasso DAP purchase and last. It uses same tubes as the new card will. AMP13 was better with DX320.

I listen to a lot of house music on my 340 using IE900 and I don't think there's any bass missing.

Same for me. It’s a more bass would be even better, rather than bass is lacking. The Amp16 will be interesting. All the Jan tubes I heard had more bass, both in size and slam

Review DX340 - A real Endgame DAP!!!

The DX340 is the latest Reference DAP, which introduces a new generation of DAPs from iBasso. For the first time, it does not use a proprietary DAC such as those from ESS or AKM, but an in-house development in the form of a 1-bit discrete DAC. This concept was first introduced at iBasso with the D16 DAC, which has already caused quite a stir worldwide and is one of the best portable sounding devices currently available. Now, for the first time, technologies from the D16 have been incorporated into a DAP and you can now enjoy a 1-bit discrete DAC with a single device. Available for an RRP of 1699€, the DX340 is a technical beast and by far the best DAP (outside of the MAX series) ever built by iBasso. Before I turn to the sonic aspects, I would like to discuss the technical features and the scope of delivery.

The DX340 continues the dual-control dual-electric concept of the DX300 series and uses a PWM DAC developed in-house with discrete components and FPGA Master 3.0 technology. This achieves exceptionally low distortion (THD+N of -119 dB) on a par with high-end desktop decoders and sets new standards for portable players with discrete components. It uses a total of 128 PWM DACs, i.e. 32 DACs per channel (L+, L-, R+, R-). This is more than 6.4 times as many as other portable DACs with discrete components. The FPGA, i.e. the heart of the DAC with all its algorithms, has been further improved compared to the D16 (version 2.0 here) to version 3.0. The logic units have been increased by a factor of 7.5 compared to the previous version! To further reduce jitter and enable precise clock control, two femtosecond crystal oscillators from Accusilicon are used. By increasing the units, it is now also possible to implement a new and exclusive algorithm for adjusting the harmonics to influence the odd and even harmonics. This means that the DX340 allows the user to customize the sound. I will go into this in more detail later.

Like the DX320, the DX340 relies on a dual battery power supply in which the digital and AMP sections are powered separately. This ensures a stable power supply, prevents distortion and reduces interference that could affect the sound quality. A new improved battery indicator simplifies charging and monitoring by providing a single charge indicator instead of two. When connected to a USB charger, the player is powered directly from the external power source, saving battery life. This innovative structure optimizes performance and sound quality. With the DX320 MAX TI, iBasso has launched the first DAP with which the batteries can be easily replaced. This is now also possible with the DX340 A DAP with which you don't have to worry in future if the batteries run out. Changing them is therefore no problem. As with the DX320, the AMP cards can also be changed here. The DX340 is also compatible with the previously released AMP12, AMP13 and AMP14 and is supplied with the newly developed AMP15. This uses 8x BUF634 to ensure a high output power. For the first time, it is also possible to connect an external 12V power supply to the amp to activate a so-called Super Gain mode. This delivers an incredible 2150mW@32 Ohm! This means that even power-hungry headphones can be driven effortlessly. There are also new AMP modules in development that can be used with the DX340 in the future, including the AMP16, which will use the popular Raytheon JAN6418 tubes. With this option, you will be able to change the sound of the DX340 even further and adapt it to your own preferences.

The DX340 is equipped with a Qualcomm Snapdragon 665 SoC, which is complemented by 8 GB of RAM and 256 GB of storage for the system and the entire music collection. This also turns up the performance dial compared to the top model DX320 MAX Ti, which is powered by the Snapdragon 660 and only has 6 GB of RAM and 128 GB of storage. The faster response of the GUI is also immediately noticeable. I think 256GB is great, so I don't even need a micro SD card to expand my music collection. Of course, you can also use cards up to 2TB via the micro SD slot if necessary. The DX340 is based on an optimized Android 13, whereas its predecessor, the DX320, still had Android 11 on board. Of course, you can also switch between a pure Android mode and iBasso's own MangoOS. I personally prefer the latter, as it sounds a little better to my ears.

The DX340 offers two different gain adjustments. The DAC Gain and the Amp Gain. The former has been adopted from the D16. The Low and High settings on the DAC only have a minimal effect on the volume changes. The Amp Gain has three battery-powered settings: Low, Medium and High. When the 12V power supply is connected, the Super Gain mode is added.

Not only has the DX340's technology been taken to the next level, the workmanship and appearance are also of the very highest standard! This is the most beautiful DAP from iBasso and one of the most ingenious devices I have ever held in my hand. The DX340 impresses with an enclosure made of high-quality 316 stainless steel, which is more robust and corrosion-resistant than 304 stainless steel and offers better acoustic performance than aluminum alloys. The precise CNC manufacturing process and the polished and brushed finish give the player a luxurious look. However, the materials used also make it heavier at 486g, compared to 310g for its predecessor, the DX320. A 6-inch AMOLED screen with a resolution of 1080x2160 ensures a brilliant visual appearance. This is the best color display I have ever seen on a DAP.

The DX340 is delivered in the usual iBasso slipcase for DAPs. Inside is the DAP with all its accessories. These include a light blue genuine leather protective cover, USB-C cable, coax cable, burn-in cable, 12V power supply, a set of protective foils, a quick start guide and a warranty card.

Before I started the sound test, I gave the DX340 a full 100 hours of break-in time with the included burn-in cable. Out of the box, the DX340 is already impressive, but the separation and especially the bass range improve noticeably after 100 hours. My sound setup this time consists of two IEMs and a pair of headphones. Can the DX340 exploit the fabulous technical capabilities of the two IEMs APX SE and Dunu Glacier and drive the Audeze LCD-4 in Super Gain mode? And how does it sound compared to the DX320 MAX Ti and the D16 solo or with PB5? And what happens if you use the PB5 directly with the DX340? Exciting questions that I will now address in the following.

iBasso continues to improve the sound with each new DX model and this time the leap is really big. My first few hours after the break-in period I was almost glued to the DX340, listening to one reference recording after another. This is a DAP where I don't worry about how it's tuned, whether neutral, neutral/warm, neutral/bright or whatever. It plays mercilessly well and naturally. From the first second the beat kicks in, there's nothing to shake about it. The APX SE and Dunu Glacier are at their best with the DX340. I don't even need to mention other DAPs in my portfolio apart from those from iBasso. It beats them all! The DX320 MAX TI and operation with D16 + PB5 is my current reference. But that's a full stack of 3 devices in total! The DX340 alone plays so damn close to the full stack and is virtually on a par with the DX320 MAX TI, although of course the sound is not identical, but “different”. That's why I'd now like to take a closer look at the differences between the DX340 and D16 and the DX340 and DX320 MAX TI. Incidentally, when operating the D16 via coax, I don't hear any difference whether DX340 or DX320 MAX TI is used as transport.

The DX340 sounds like a fusion of the DX320 MAX TI and D16. It has inherited the attributes of instrument separation and the physicality of individual instruments from the discrete DAC implementation of the D16. It also has the slightly more energetic playing style of the DX320 MAX TI. It plays slightly brighter than the D16. You can hear the virtues of the discrete DAC, but not as strongly as with the D16. This has a slightly more powerful bottom end and gives individual instruments even more fullness. The soundstage is at the same level. The DX340, on the other hand, sounds a little faster, as it is softer in the bass and more lively in the treble. The DX320 MAX TI still has the greatest stage imaging, the ROHM DACs can simply do that and I appreciate that so much about them. The MAX TI also has the fuller mids and the more powerful slam and a little more low bass. The DX340 counters this with better instrument separation and the resolution is also slightly higher. The high edge definition simply makes it easier to hear micro details.

Incidentally, the DX340 offers 5 different settings (H1 to H5) for harmonic adjustment, which can be used to slightly influence the sound. As with all filters, this is not a night and day difference, but very subtle. I personally use it with the standard setting H1 (original), as this gives it the most transparent sound.


Here are the small differences compared to H1:

H2 (Natural): slightly less treble. The sound is a little warmer and bassier. Sounds the smoothest of all filters. Recommended for very bright IEMs.

H3 (Even+): similar to H2, but with less filter effect.

H4 (Odd+): Even higher instrument separation like H1 and liveliness in the highs

H5 (All): As the name “ALL” suggests, this filter combines H3 and H4. More fullness in the mids and greater illumination in the highs. Not as smooth as H3 alone.


What constellation is still missing? I haven't even mentioned the PB5 yet. As described in my PB5 review, the PB5 at the end of a D16 chain brings richer midrange colors with more texture and body. In addition, a more holographic stage image and a stronger bass range. In DX340 + PB5 mode, the edge definition increases even further. The individual instruments sound fuller and the previously softer bass kicks more strongly and the low bass increases. This is a real dream combination when used with the APX SE. The mids are hard to beat in terms of richness of timbre and analog quality. And the bass has such a brilliant attack, it's amazing! Only the D16 + PB5 can produce even better bass. But this combo also requires a transport DAP, so 3 devices again!

Wait, there was something else, the Super Gain mode, right! How does the DX340 actually perform when used with more power-hungry headphones? Super Gain mode currently only works in Android mode. Although it can be switched on in MangoOS, it has no effect. iBasso is aware of the problem and is already working on a solution to provide an update. The Audeze LCD-4, the “Bass King”, recently found its way back into my collection. How I regretted selling it at the time and have now fortunately found and purchased another LCD-4 in top condition from 2016. With its 200 ohms, it is not easy to drive. But I have to say that I enjoy it even in battery-powered mode with high gain. Of course, in my stationary chain with a Niimbus US4 or Feliks Audio Envy, the sound is a clear step up, especially in the bass range. Stop, but what's going on! Just connect the 12V power supply and activate the Super Gain mode and the LCD-4 starts to wake up! Yes, there it is, that brute low bass range that I know from using the Niimbus US4. Then I got the idea that I also own the Ferrum Hypsos power supply. And my brief impression of the WANDLA GSE has already shown what linear power supplies can achieve in terms of sound gain. The DX340 uses a 3.5x1.35mm socket. My Hypsos only has a 5.5mmx2.1mm plug. But nothing easier than that, you can buy adapters in all possible combinations from Amazon. Quickly set the Hypsos to 12V and then the Super Gain mode is already active. My goodness, it's hard to believe! The DX340 plays even cleaner than the power supply included in the package, with greater stage imaging. But above all, the control in the bass range increases noticeably. Cool, an LCD-4 at this level with a mobile DAP - that's really great! And in direct comparison with a Niimbus US4, the differences are really only small, the DX340 plays so close to it.

With every iteration of DAPs from iBasso, the technical capabilities are constantly being improved. Compared to the previous version, I think the difference is huge. Despite inflation, the price has only ever risen slightly from EUR 1599 to EUR 1699, which is perfectly acceptable. For this price you get a DAP that is technically one of the best on the market. It's damn well made and the sound is in heaven. I think iBasso's move away from the usual DACs from ESS and AKM has shown what potential is still hidden in our digital music libraries. I can't wait to see what else iBasso comes up with for the next MAX model to push performance to the next level.

The DX340 offers two different gain adjustments. The DAC Gain and the Amp Gain. The former has been adopted from the D16. The Low and High settings on the DAC only have a minimal effect on the volume changes. The Amp Gain has three battery-powered settings: Low, Medium and High. When the 12V power supply is connected, the Super Gain mode is added.

Not only has the DX340's technology been taken to the next level, the workmanship and appearance are also of the very highest standard! This is the most beautiful DAP from iBasso and one of the most ingenious devices I have ever held in my hand. The DX340 impresses with an enclosure made of high-quality 316 stainless steel, which is more robust and corrosion-resistant than 304 stainless steel and offers better acoustic performance than aluminum alloys. The precise CNC manufacturing process and the polished and brushed finish give the player a luxurious look. However, the materials used also make it heavier at 486g, compared to 310g for its predecessor, the DX320. A 6-inch AMOLED screen with a resolution of 1080x2160 ensures a brilliant visual appearance. This is the best color display I have ever seen on a DAP.

The DX340 is delivered in the usual iBasso slipcase for DAPs. Inside is the DAP with all its accessories. These include a light blue genuine leather protective cover, USB-C cable, coax cable, burn-in cable, 12V power supply, a set of protective foils, a quick start guide and a warranty card.

Before I started the sound test, I gave the DX340 a full 100 hours of break-in time with the included burn-in cable. Out of the box, the DX340 is already impressive, but the separation and especially the bass range improve noticeably after 100 hours. My sound setup this time consists of two IEMs and a pair of headphones. Can the DX340 exploit the fabulous technical capabilities of the two IEMs APX SE and Dunu Glacier and drive the Audeze LCD-4 in Super Gain mode? And how does it sound compared to the DX320 MAX Ti and the D16 solo or with PB5? And what happens if you use the PB5 directly with the DX340? Exciting questions that I will now address in the following.

iBasso continues to improve the sound with each new DX model and this time the leap is really big. My first few hours after the break-in period I was almost glued to the DX340, listening to one reference recording after another. This is a DAP where I don't worry about how it's tuned, whether neutral, neutral/warm, neutral/bright or whatever. It plays mercilessly well and naturally. From the first second the beat kicks in, there's nothing to shake about it. The APX SE and Dunu Glacier are at their best with the DX340. I don't even need to mention other DAPs in my portfolio apart from those from iBasso. It beats them all! The DX320 MAX TI and operation with D16 + PB5 is my current reference. But that's a full stack of 3 devices in total! The DX340 alone plays so damn close to the full stack and is virtually on a par with the DX320 MAX TI, although of course the sound is not identical, but “different”. That's why I'd now like to take a closer look at the differences between the DX340 and D16 and the DX340 and DX320 MAX TI. Incidentally, when operating the D16 via coax, I don't hear any difference whether DX340 or DX320 MAX TI is used as transport.

The DX340 sounds like a fusion of the DX320 MAX TI and D16. It has inherited the attributes of instrument separation and the physicality of individual instruments from the discrete DAC implementation of the D16. It also has the slightly more energetic playing style of the DX320 MAX TI. It plays slightly brighter than the D16. You can hear the virtues of the discrete DAC, but not as strongly as with the D16. This has a slightly more powerful bottom end and gives individual instruments even more fullness. The soundstage is at the same level. The DX340, on the other hand, sounds a little faster, as it is softer in the bass and more lively in the treble. The DX320 MAX TI still has the greatest stage imaging, the ROHM DACs can simply do that and I appreciate that so much about them. The MAX TI also has the fuller mids and the more powerful slam and a little more low bass. The DX340 counters this with better instrument separation and the resolution is also slightly higher. The high edge definition simply makes it easier to hear micro details.

Incidentally, the DX340 offers 5 different settings (H1 to H5) for harmonic adjustment, which can be used to slightly influence the sound. As with all filters, this is not a night and day difference, but very subtle. I personally use it with the standard setting H1 (original), as this gives it the most transparent sound.


Here are the small differences compared to H1:

H2 (Natural): slightly less treble. The sound is a little warmer and bassier. Sounds the smoothest of all filters. Recommended for very bright IEMs.

H3 (Even+): similar to H2, but with less filter effect.

H4 (Odd+): Even higher instrument separation like H1 and liveliness in the highs

H5 (All): As the name “ALL” suggests, this filter combines H3 and H4. More fullness in the mids and greater illumination in the highs. Not as smooth as H3 alone.


What constellation is still missing? I haven't even mentioned the PB5 yet. As described in my PB5 review, the PB5 at the end of a D16 chain brings richer midrange colors with more texture and body. In addition, a more holographic stage image and a stronger bass range. In DX340 + PB5 mode, the edge definition increases even further. The individual instruments sound fuller and the previously softer bass kicks more strongly and the low bass increases. This is a real dream combination when used with the APX SE. The mids are hard to beat in terms of richness of timbre and analog quality. And the bass has such a brilliant attack, it's amazing! Only the D16 + PB5 can produce even better bass. But this combo also requires a transport DAP, so 3 devices again!

Wait, there was something else, the Super Gain mode, right! How does the DX340 actually perform when used with more power-hungry headphones? Super Gain mode currently only works in Android mode. Although it can be switched on in MangoOS, it has no effect. iBasso is aware of the problem and is already working on a solution to provide an update. The Audeze LCD-4, the “Bass King”, recently found its way back into my collection. How I regretted selling it at the time and have now fortunately found and purchased another LCD-4 in top condition from 2016. With its 200 ohms, it is not easy to drive. But I have to say that I enjoy it even in battery-powered mode with high gain. Of course, in my stationary chain with a Niimbus US4 or Feliks Audio Envy, the sound is a clear step up, especially in the bass range. Stop, but what's going on! Just connect the 12V power supply and activate the Super Gain mode and the LCD-4 starts to wake up! Yes, there it is, that brute low bass range that I know from using the Niimbus US4. Then I got the idea that I also own the Ferrum Hypsos power supply. And my brief impression of the WANDLA GSE has already shown what linear power supplies can achieve in terms of sound gain. The DX340 uses a 3.5x1.35mm socket. My Hypsos only has a 5.5mmx2.1mm plug. But nothing easier than that, you can buy adapters in all possible combinations from Amazon. Quickly set the Hypsos to 12V and then the Super Gain mode is already active. My goodness, it's hard to believe! The DX340 plays even cleaner than the power supply included in the package, with greater stage imaging. But above all, the control in the bass range increases noticeably. Cool, an LCD-4 at this level with a mobile DAP - that's really great! And in direct comparison with a Niimbus US4, the differences are really only small, the DX340 plays so close to it.

With every iteration of DAPs from iBasso, the technical capabilities are constantly being improved. Compared to the previous version, I think the difference is huge. Despite inflation, the price has only ever risen slightly from EUR 1599 to EUR 1699, which is perfectly acceptable. For this price you get a DAP that is technically one of the best on the market. It's damn well made and the sound is in heaven. I think iBasso's move away from the usual DACs from ESS and AKM has shown what potential is still hidden in our digital music libraries. I can't wait to see what else iBasso comes up with for the next MAX model to push performance to the next level.

Oh Yeah

Thanks for the great write-up, giving me some insight in the H-settings and DAC gain was welcome. Good to hear it does well withthe PB5, I ordered one this morning, seems to be quite a bit smaller than my C9ii and, well, less settings (which sometimes is better than more )

@Trance_Gott how close is the pure dad performance relative to your wandla? Thinking about using ibasso as an all in one, but if the gulf is still big enough with desktop gear, I may have to go that route.

IMO, desktop gears in general (or specifically using hd800s and MDR Z1R) only advantages is the Amplifier.

DAC sections, my D16 is in a strong lead over my modified desktop DAC.

I have been trying to find out about the reasons to make senses of what I am hearings. I think I found it... but it is a very long post and complicated ....may not be so enjoyable to post or read either

Very different sounding WANDLA is faster more ESS like DX340 more analog overall. I like both presentations. WANDLA GSE has the Spatial Imaging which I love. Hope it someday is available on a mobile device. It's that good with some headphones and records. But there are times it makes the presentation too bright. So I don't use it 100% of the time.

For those who wish the 340 had more bass, doesn't the Android side have EQ available?

 

[mattclarke18]

Same for me. It’s a more bass would be even better, rather than bass is lacking. The Amp16 will be interesting. All the Jan tubes I heard had more bass, both in size and slam

I have the Cayin DAP with same tubes and it is very lacking but I am sure iBasso will do a better job. The tubes do not take a lot of power I can say that and do not get hot at all. Amp13 was better sounding to my ears. The Cayin has a lousy DAC and AMP section is could be a lot better. They did manage to remove the issues that are with most tubes but at the cost of no wifi or BT and its a locked system and local playback only. I am going to list it for sale.

 

[mattclarke18]

I listen to a lot of house music on my 340 using IE900 and I don't think there's any bass missing.

That is good to know. If you had a DX260 you could compare. DX260 is not a bad DAP and with Swissbit its even better. Only been out for 1 year. I think getting a D16 or D17 and using my DX260 would make more sense for me. Really don't need another DAP as the DX260 would just be source and can still be used stand-alone. Not something that I would take out of the house and I would be fine with that- don't take my DX260 out of the house now. I have the DX180 and BT with my phone for that. The D17 could be even better than the D16 too especially if they allow for AC power as well as battery to boost AMP section to match DX340.

Yes bass can be EQed. I use Wavelet now as I like the tuning of a different IEM to the one I actually have. It enhances Maven II - more bass and improves stage nicely.

Hello. I'm going to choose between Chord hugo 2 and ibasso dx340. However, I'm undecided. Which one do you think I should buy? Has anyone listened to both?

Hello. I'm going to choose between Chord hugo 2 and ibasso dx340. However, I'm undecided. Which one do you think I should buy? Has anyone listened to both?

Very different machines. As DAC the Hugo 2 is definitely better, in my opinion. It’s the best portable/transportable machine ever created: it’s incisive and musical at the same time.

From a convenience point of view a dap might be better, and the dx340 is an exceptional one
