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.
