Interfacing Computer Music to D/A Converter ?

USB DACS can be purchased for less than 30.00 Alot Depends on what happens next, or what you really want to do. I sell the Dared MP-5 Tube Dac Amp. Its a all in one piece using the burr brown 2702 DAC. The total system is around 370.00 Actually USB direct to a DAC is a great way to go as there is no jitter that you might experience with S/PDIF outputs. It depends on how much of a audiophile you are and how efficient your speakers are, as the more efficient the more they allow you to hear the flaws in equipment.

As pointed out, you do not need to spend a ton of cash on a good (USB) DAC, especially if cosmetic issues are not that important. Along with the usual suspects, offering some choices in the $1000+ categories (Wavelength, Empirical, Apogee, Hagerman, and others), there's also a large contingent of both DIY and Low-Tech designs coming out of China, based on excellent NOS chips, and sound design. Tvad recently pointed me to one he's been trying with great results, made by MHTDLab, and reviewed here on Enjoy the Music. These sell on eBay regularly, the USB version of the Constantine, using the TDA1545A chip, as does the Paradisea tube-buffered version Tvad has. The USB Constantine is $399. There is also another USB DAC he sells based on the TDA1543 chip called the Dialogue II that is $299. This is the same chip used in the NOS AudioMirror DAC that has garnered some outstanding real-world comments both here and on other sites. The board for that DAC is also outsourced from China, and is available as a full on reproduction of the AudioMirror design as the DAC-AH which can be purchased for under $200 direct from China (not a USB DAC though). On the MHTDLabs units, Grant told me he got his in three days from Taiwan, superbly packed and without a hitch. The guy's abundant 100% positive eBay feedback suggests this is the norm. Grant seems to like his alot - perhaps you can contact him if it interests you to pursue further, or he can chime in here. If you are a DIY guy you can get kits to build a dimilar DAC for much cheaper. I won't go there as I doubt that's what the poster is looking for.

I am Curious about adding the USB interface to a Audiomirror / Dac-ah ? is there a way to get it modded to add the usb direct, even if you have to eliminate the toslink or coax digital board ?

You may want to contact Vlad at Audio Mirror about thatcontact@audiomirror.com. You can certainly use an external conversion like a Waveterminal U24, Emprical USB Freeway, HagUSB or similar USB-S/PDIF convertor.

Undertow - I can add high-performance USB to practically any DAC or even the DEQX, but the cost will depend on what is inside the DAC. The correct implementation is USB to I2S to D/A chip. Doing this has its pitfalls, namely muting and sample-rate decode. Unless these issues are addressed properly, functionality of the DAC will be lost or it may even output damaging DC at times. I would NOT trust this to an amateur modder. If the DAC contains a CS8414 or AD1896, then it makes it easier as I have boards designed already for these.

I already add USB or I2S interfaces to these routinely:
Benchmark DAC-1
Lite DAC-60
DEQX
