    You need to read the title of this thread. He's requesting USB for an Audio Note DAC that uses an old codec. You don't need to worry about its support for DSD over PCM, etc. Its computer world contemporary is a Windows 98 Pentium II 233 with a Sound Blaster AWE64 Gold plugged into one of the ISA slots.

    The Wyred µLINK USB to S/PDIF Converter is a nice option. Good clocking for reduced jitter, good build quality and reasonable price.

    I think we can probably do without this crap-talk and focus on the point of the thread, no? OP has a DAC from a highly regarded company and he’s obviously chosen it for a reason. Moving on.

    fact-talk.

    The digital input to the AD1865N in the Audio Note is being used much like it would be on a 1992 CD player (and much like in the 1999 AN DAC 2.0):

    It is certainly possible to use your own digital front end and DSP to say, use 48 of these chips to build a DAC that supports DSD via DOP, 384kHz over USB, etc, but that is not done in the Audio Note:

    It actually IS a very old computer source like a AWE32 that may be able to maximize this DAC and properly supply it with an 18 bit S/PDIF signal.

    I am very interested in your impressions. Any update?

    If you can wait until next weekend I would like to do a little A/B comparison between the Abbas and the X-SPDIF2 and then I will provide some insight. (My wife will travel to Croatia then, so I’ll have some time to be an audio nerd.)

    In the meantime I can say it’s a very nice piece of equipment and Abbas is great to deal with. It’s fairly large for what it is, but that’s not really a bad thing. Actually I think a slightly larger enclosure might even be a benefit given the proximity of the tubes to the transformer.

    Very cool. I can’t believe I finally found someone trustworthy who can compare it to a really nice low jitter source. Thanks!

    Same, for three years. Very happy with it.
