The CEntrance DACport is a USB-fed DAC/headphone amp that offers upscale 24-bit / 96kHz resolution via USB, a salient selling feature for any portable computer DAC unit. The DACport has a cylindrical, cigar-like shape featuring a full-size headphone output on one end, a USB connection and an LED power light on the other, and a small rubberized volume control dial on top. The design of the DACport got good reviews overall as its ease of connectivity and small size make it easily transportable for computer listening both at home and at the office, sliding unnoticed into a shirt pocket for the commute. The DACport's sound signature is slightly 'forward' and analytical sans audible harshness and delivers especially superb audio synergy with darker, more 'laid-back' headphones like the Sennheiser HD650. It's also got plenty of power to drive high-impedance cans like the Beyerdynamic Tesla T1 or Sennheiser HD800 to loud listening levels, a big plus for a tiny portable headphone amp.
What became most apparent to our HeadRoom ears using the CEntrance DACport was an extremely broad soundstage image with excellent musical separation and precise timbral accuracy. While the low bass may lack some sense of roundness or supple warmth, bass texture is beautifully apparent while the mids and highs maintain a cleanly delineated clarity that sounds strongly defined without strident grain or edge We all agreed that the CEntrance DACport holds a solid spot in our HeadRoom offerings given its uber-portability, precise musical detail, broad soundstage image, full 24-bit/96kHz capabilities and plethora of high-end headphones it can effectively drive. We think it pairs great with any cans tending towards a warmer tonality and the DACport will really bring them alive with full detail and a natural sense of ease. With more 'neutral' analytically-leaning cans like the AKG K701, Tesla T1, or HD800, you'll still get a very well-detailed, albeit slightly stringent presentation. Great engineering and design from Michael Goodman and team -- kudos, CEntrance!

Recommend Product: Yes
Pros: Portable and simple
Cons: No HeadRoom crossfeed circuit
Update: I've been using the DACport in combination with my Total Bithead and have been very pleased with the results. I connect the DACport to the computer and run its output to the Total Bithead. The combination drives my Sennheiser 580's better and I get the benefit of the Bithead's crossfeed circuit. I still think the DACport is a good deal and remain pleased that I purchased it.

Pros: Portable, solid.
Cons: Require external power for ipad
I was looking for a tutorial on how to get 24/96 audio from an iPad. No one could fully help me and a tutorial doesn't exist...so here is how I did it. You need an iPad 2 not an original. I confirmed with Centrance that the DaqPort works direct with the iPad through the USB camera connection. Full 24/96. You do not need to re-flash the DacPort to 16/44.
I downloaded music from HD tracks at 24/96 as FLAC files. iTunes does not play FLAC. I bought the iPad FLAC app called FLAC Player. You do use iTunes to move files from your computer to your iPad FLAC player. Pretty straightforward. FLAC player works direct out of the headphone jack but I'm fairly sure the internal iPad D/A down coverts to 16/44.
The DaqPort runs from USB and bypasses the internal Dac. You use a camera connection kit for iPad to get direct USB. Unfortunately the iPad USB will not drive the DacPort (power wise). I split the USB out using an Apricorn USB power splitter. I also bought a Trent IMP1000 power pack. This about $70 but is great for extra power for iPads, phone, etc. So it is worth having anyway. Black USB to iPad, grey USB to battery, output to the DacPort cable. Pretty easy. The DaqPort cable is very long, a shorter one would be neater especially since you have an extrnal battery to put somewhere. Headphones into DaqPort.
It works! I tried both FLAC player music and iTunes. Both work. iTunes actually recognizes the DacPort by name. Now what data rate comes out of what would require instrumentation but I believe the DacPort does everything at 24/96. It clearly bypasses the internal dac and you get a class A external amp.
Initial listening with shure 535 is excellent. Very clean and it delivers a much larger sound field, especially for in ear headphones. This combination is louder than you will ever need as these headphones are very sensitive. Reportedly the DacPort works with high z phones as well. More critical listening to come!
