I see. Thank you all for your insight!

One last question though, is it possible then to have two different cards to
work as a single device (via asoundrc + JACK) if they would be linked with
some kind of a word-clock that would ensure their hw sync (obviously
assuming that they offer such feature)?

 Having meddled some with this myself, and as Steve intimated, without
 the availability and ability of word-clock syncing between whatever
 cards being used in the multi card config, they drift at whatever
 settings you use from Jack and it results in distortion, xruns and all
 kinds of other nasties. I played with 2 identical SB Live 5.1's for some
 time in hopes of getting the "cheap fix" only to find that the oldest
 principle in life applies; You get what you pay for!"
