    this thread is as much hardware as it is software as it is audio.....

    I think software guys are needed here maybe, but might never see this thread unless they happen to also be audiophiles.... I'm thinking it might not be a bad idea to start a thread in the software forum about the usb communication end of this may be.... jjust a thought...

    good point. Although last time I tried to post audio realted software in there it went unanswered unless it was directly associated with a frontend.

    a hardware thread in the hardware forum is a good idea. Once we have an idea on what hardware, THEN we can go to the software side of things...how it's interfacing and what not.

    Does that make sense?

    yeah, I guess as I posted that I also realized that unless a software guy is really interested in the same goals then there would be no reason for involvement...

    hahaha...ooops. I got a little excited

    USB/IS2 to Multi-channel DAC (8 channels NOT 7.1) driver support needed

    I guess we can let it hang and see if anyone bites or delete it.

    I guess hardware makes sense... at some point someone is going to have to develop a circiut board & invest in actually prototyping something.... of course, first there has to be a plan of action.... the component layout & diagrams need to be finalized.. it's usually cheaper to do stuff like this in multiples.... maybe a prototype can be built with a project board, but if the components involve smd's or dual layer boards then it'll have to be sent out.... even to build a board to test...

    kinda hard to go building hardware without knowing the software end is going to be worked out.....

    so what's the plan red, are you building & investing here? at some point this may go from talking to actually doing... is this what your after?

    well we should get a well planned out outline before we start the new thread. Then stand strong to only figuring out what is needed to accomplish our goals.
    so to recap design goals (please add to this as there are a bunch of posts i've skipped over)
    USB DAC
    I. Hardware
    A. 8 stereo chans
    1)24/bit
    2)192kHz
    B. usb 2.0
    C. opamps
    1)audiophile grade
    2)Replacable opamps
    D. outputs
    1) min 4vrms (8vrms ideal)
    2) balanced output (i know..it's a long shot) but we are talking audiophile grade here)
    E. Processing
    1)no hardware processing
    F. Power Supply
    G. Volume Control
    II. Software
    New System in progress:
    M10k
    Phaze TD1500 ~> Dynaudio MD130
    Phaze TD1500 ~> Seas g18rnx/p
    Zapco Ref 500.1 ~ 12" tc-9
    Behringer DCX2496 ~ Envision Electronics psu
    Transflective Xenarc

    another avenue we should investigate is this unit here:
    http://www.macrom.it/EN/amps/extreme/ext.adsp_82.htm

    maybe it will spark some ideas or give us some answers
