    I'm pretty excited for this fully assembled soekris dac. Alvin on xtremeplace posted a couple diagrams of the design. Also he bought so many dac pcbs from soekris the europe web site is out of stock now of the 0.02% version
    C'mon you audio 1 percenters should hop on the group buy with me :) DHL shipping to usa was only like $60 or so

    Is this thing better than the upcoming $650 Soekris-assembled DAC/Amp?

    Looks pretty cool. Fingers crossed, he does proper testing, before it ships. For the original board a few folks blew their speakers/amps due to various operational quirks.

    The 1.05 firmware and rev 3 pcb of the diy board seem pretty stable now, no click pops etc. Hopefully this new board is close enough to the diy one that he was able to use what he learned to make it a less buggy product

    Ugh. that's concerning lol. this dac is exactly what I'm after those last days ( Good value, small , simple with potential good SQ ) . Should I do some testing with my O2 before to wire it to some more pricey amps?

    Is the Line out output fixed or controlled by the volume pot ?

    soekris says the headphone out on his usb powered dac is good
    "I'm very very happy with the sound of the dac1101, several small improvements, although the biggest improvement compared to a dam1021 is the new output buffer / headphone amplifier, in my humble opinion it's kinda fantastic, can drive 4V RMS into 32 ohm from just +-6.5V, fully discrete, no nfb, high bias class AB, my Sennheiser HD650 have never sounded better.... I now need to upgrade my headphones, maybe the new HD800 S, good to have a company to pay :)

    I'm considering making an add-on balanced output buffer / headphone amplifier for the dam1021 based on that amplifier design, any interest ?"

    @uncola, as You said , comparison against the GOv2 will be interesting. :)

    Looks like a really cool unit, but I'd be much more interested if the output impedance was less than 3 ohms. If the GOv2+ Infinity ends up being a disaster I might consider getting one of these for traveling nonetheless.

    I wonder if we could bribe Mike Moffat to put the closed form filter in this thing. Or just make Schiit pull something out like this that's all in-house. I like bribery, but a USB powered multibit DAC/amp from schiit sounds pretty neat.

    A higher end fulla seems like a logical product

    There's 3 spots left in Alvin's prebuilt soekris with built in Lehmann black cube linear clone headphone amp if anyone wants to join. He has a website now too. WWW.vinshineaudio.com
