    I was wanting to know if all soundcards mantain the purity of digital
    signals fed into them ?

    Say I have an entry level 4 I/O recording interface. (I actually have
    one) which has SPDIF input and output. I purchase a good 2 channel ADDA
    external converter. Feed the soundcard with this converter and monitor
    off it too.

    Will now, this comparitively cheap card give performance equavilant to
    a better card, like an RME, being fed with the same SPDIF signal ??

    thank you.


    p.s. the card in question is the esi audiotrak maya 44 mkII.

    ran a test using RMAA. here are the results :


    please comment.

    the dynamic range offered by these converter is a poor 90dB. But i
    figure there have been ppl. doing a lot of good work before 107+ dB
    converters became norm. Just an afterthought.
