Pros: Good looks and quality sound

Cons: Need to load PC software

I had considered many of the comments made by fellow members regarding what to buy for under a grand that would improve my listening station - all replies were good and appreciated, The first issue was the need to replace a HeadRoom Total BitHead and a HeadRoom Supreme upgraded to reference amp some years ago. This is when the Teac UDH01-S Digital to Analog Converter with USB Audio Interface became my solution. It allows 3 digital inputs USB, coaxial, and optical with a selector button to chose the source and has balance and unbalanced outputs The headphone volume control with 1/4 jack is placed on the front panel as well as syncs on any signal from 44 to 192 with LEDs indicating it has locked on to the signal. The details of what is inside is listed below but I think of what does it sound like followed by what does it look like then can I afford it in that order. So I will say a very well known headphone amp/dac engineer said it should be sound very nice based on the details of what is inside the box for those who go beyond Thevenin's theorem.  What I didn't like is having to install software to make the USB work and that it had to be downloaded from a Japanese site rather than an including a disc sort of sucks. And as long as I am being picky a stepped volume control would have been a nice upgrade, but it isn't a big deal.  So, why I like the Teac is it doesn't sound like most OP AMPs or tubes but it is close and it is always ready to play. The looks are nice despite a somewhat faux glass and metal but again how does it sound is why I bought it. Now if I wanted portability I clearly would have bought the HeadAmp offering for roughly the same money.  I have Krell gear and have owned some of the best tube stuff but frankly it is the sound not the constantly farting with replacing tubes and re-biasing that I enjoy. I liked the idea of the Pass units but the listing on the sight turned out to be either no longer valid or they didn't bother to reply (very disappointing) . As a side bar because like many audio nuts I have often been caught on the wrong side of changing technology and thought newer must be better but really devoting time to listen without caring so much if this is the best possible is my solution.

7/15 Follow up - the TEAC unit developed some type of glitch allowing it to randomly flip back to the PC speakers despite the DAC lock still being illuminated. To resolve the problem you had to unplug and reinsert the usb cable. TEAC was less than responsive in helping - despite doing everything thing I could imagine including changing PCs and cables, I was forced to return the unit. Fortunately it was bought from Dedicated Audio so there weren't any issues in returning it.  

 

  I have replaced it with a demo PS Audio Digital Link III which has performed beautifully without the slightest issue. The software to connect via usb to the PC is internal and requires nothing on the user part. The build quality is much more solid than the Teac but I have been hard pressed to hear any sound improvement.  There are still PS Audio units available for $500 (same price as the TEAC)

USB input is TE8802L - based, which is good, but NOT compatible with Linux computers or any other Linux-firmware-based gear, like for instance, the squeezebox toux with the enhanced digital input app (which does support async usb to other DACs), and there are certainly other nice transport that are linux based. That is a real drawback. See this thread for the discussion:

And write TEAC and GFEC as well as your seller, as suggested in the mentionned thread, as pression of many will help to push them to finally develop a driver!!!
I suggest a mail as this example, if you eventually consider buying such a DAC.
Mail it to av-tsc-ip-sales@teac.com and custser@teac.com :
Dear TEAC-support team, I am wondering, if the USB-input of UDH01-S is Linux compatible. My goal is to buy a DAC, that I can connect to a Linux-computer over asynchronous USB. However, as far as I read, the USB-input is based on the TE8802L - chip. And this is said, not to be Linux compatible. Can you eventually provide for a suitable driver? As for the rest of features, the UDH01-S really looks promising. Thank you, sincerely yours......
This was on my list for upgrades...

The Teac UD-H01 WORKS with Linux (using Ubuntu 12.10) no drivers needed. Works perfectly with PulseAudio (44/48k) and ALSA (bit perfect 44 to 192k). Been using it with Audacious and XMBC and it automatically changes sampling rates according to the song being played.
Even my Teac unit works on Ubutu and it actually works better than Windows.
I've had my HD-01 for a few months now and it sounds beautiful when paired with a Schidt Mholnir balanced amp and HE-500 balanced headphones. I'm currently in the process of installing a Tripath 2020 amp board into the HD-01's case with a 4-pin XLR connector as an internal high power balanced headphone amp.
