CEntrance DACportable review

*CEntrance DACportable with Campfire Audio Andromeda IEM.
I emailed Michael at CEntrance with a few questions about the DACportable that they had kindly sent Head pie for review and he emailed back a nice summary of what the DACportable is:
`The DACportable is basically a HiFi-Skyn, in a universal package (not tied to any particular phone model, it works with Mac, PC, Android and iOS).
HiFi-Skyn pioneered our newest Amp Extreme (TM) circuit, a modified Class A circuit, that takes its power from an extra clean, bipolar, 16V power supply. The internal Li-PO battery gives us plenty of clean power that we later transform into 7 different voltages for different parts of the product. Separating the power supplies allows us to achieve perfect isolation between analog and digital circuitry. This offers lowest jitter, noise and distortion, and improves soundstage, definition and clarity.
The EQ is subtle and musical. It's the same hardware circuit as in the HiFi-M8, which was so popular and well-regarded when it was introduced. Nothing beats well-designed analog circuitry in the age of digital audio.
With the EQ, we've kept a low degree of boost, just enough to accentuate the music, but not to much to overwhelm the senses. The bass switch offers a energetic boost, perfect for dance music enjoyment, while the high switch engages a smooth shelf that adds sheen to the very top of the range. This helps definition and adds sparkle for all music types, and allows better matching to various headphones.` - CEntrance.

USE
The CEntrance DACportable is compatible with Mac, Windows, Linux, Android, iOS.
The ipod touch 5G seems to require the CCK.
*I preferred the sound of the lightning to Micro USB cable over that of the CCK set up. It had better clarity and detail.
Value
At US $349 it is priced quite decently in the scheme of all things audio.
The build is excellent.
Size is portable, although I would like it to be a bit thinner...but that is the price to pay for a decent sized battery and enough output power for a full bodied sound, and also so that the ipod touch/iphone/ipad/android devices battery does not drain.
Audio is typical of the CEntrance in-house sound we have been accustomed to: Clear, great details, full bodied, fairly neutral.
If the DACportable in terms of its size, power and quality of sound makes the larger DAC/Amps on the market quite redundant.
Sound
As per usual I let the device acquire a decent amount of hours and playing time before completing my review, this is to check for any possible changes in the sound signature as demanded by a percentage of readers of audio reviews
I used a variety of IEMs in my testing (some of them pictured in the photos) and also two headphones: the MEZE 99 Classic and the ATH-ESW11.
The DACportable has already been described by Michael at CEntrance as `basically a HiFi-Skyn, in a universal package`.
This is true for sure, although it seems to have been tweaked a little more as is to expected, it sounds slightly clearer and less warm than the Hifi Skyn to my ears.
I preferred the sound from my ipod touch 6G straight to the DACportable over the ipod touch 5G with the CCK cable. It seemed to have slightly more sound stage, depth and a 3D effect.
*Using the Campfire Audio Andromeda which has been my go to IEM as of late all I can say is that everything seems to be where it should be sound wise. Bass is full but not over riding, vocals are nicely balanced with the music and slightly forward, large sound stage, excellent and effortless width and height, fast decay but lingers where it should, mids are lush, sweet but also full of clarity and tight, treble is perfect as it reaches out just far enough.
The DACportable is a large sound in a small package.
Bass is fast and accurate, punchy when it is present and needed.
Mids are clear, crisp and not bleeded out.
Treble is well balanced, non fatiguing and extends far enough to be pleasurable and satisfying to the listener without encountering any sibilance.
Sound stage is very wide, with excellent instrument placement and separation.
Virtually zero hiss on low gain with sensitive IEMs such as the Campfire Audio series.
A 3D-ish, holographic listening experience. Height and depth extends tall and wide.
*Using the Jomo 6R IEM which is a more airy experience. I enjoyed the laid back sweet, sensual sound whilst listening to Lana Del Rey. The key words being clarity, detailed and wide.
*With a more moderately priced earphone such as the Shozy Zero everything is a bit less of course, the highs partly more subdued, and the sound stage more medium.
As it is a single driver I was able to use high gain and this bought back much of the 3D effect, depth and width. Still great clarity, detail, separation and performance. Very musical.
Meze 99 Classic headphones pictured with the CEntrance Hifi-Skyn.
*Next I tried the Meze 99 Classic headphones on low Gain they were a bit quiet and un energetic as to be expected as the low gain setting is more geared towards sensitive IEMs.
Switching up to the more appropriate High Gain I got what I was expecting, a decently wide sound stage, great details and instrument separation.
*The Campfire Audio Nova performed excellently on both low and high gain.
Using high gain gave the DACportableextra oomph using gain 2 which gave it a bit more punch at low volumes.
On low gain it was also fantastic but retained more clarity and coherancy at higher volumes.
The Nova sound is XXx, more centered around the bass and mids, light on the treble.
I have found the Nova to be picky at times with sources and daps, but it seems to be a nice fit with the DACportable.
Overall
For those who have owned a CEntrance product before you will already be familiar with their products` excellent build quality and the CEntrance in-house sound signature.
The DACportable takes all the great points of the previous CEntrance portable range from the Hifi-M8 to the Mini-M8 and the more recent Hifi-Skyn and re-imagined them in a smaller foot print.
Keeping the Hifi-M8 power and hard EQ switches, the portability of the Mini-M8 and its friendliness towards IEMs, added the new AMP Extreme(TM) of the Hifi-Skyn and made it universal in its usage with Mac, PC, Android and iOS.
Though a bit chunky due its height, the overall size is well within acceptable parameters.
With a solid build and silky finish of the scratch-resistant, lightweight anodized aluminum it is easy on the eyes and feels robust in ones hands.
The Amp Extreme (TM) has oodles of power to drive most headphones to the users satisfaction.
With my sensitive Campfire Audio Andromeda with no music playing on gain 1 there is virtually no hiss. Very near a black back ground.
Whilst the DACportable retains the CEntrance in-house sound signature, it appears to my ears to be a lighter, clearer and more detailed product. It loses a little of the warmth that some of the earlier CEntrance products` had but retains the power and fullness of them.
I found the DACportable overall to be an excellent performer on all points, this is my favorite CEntrance product release so far. CEntrance has taken all that is good from their earlier products and folded it into this smaller package.
