alsa_in/out programs can yield lower latency than jackd itself.
and i doubt, that anyone can hear the artifacts.
the website is for the version that came with jack 0.116.x
but the new algorithm is a lot better.
I'm looking on how to sync the two cards,
delta-1010 and delta-66.
AFAIK, no matter the method, it seems one must sync them using spdif
(don't think this is needed on Windows, but perhaps that has to do with
proprietary drivers?).
If you want to use these two cards together, then syncing with SPDIF is
pretty much required. The alsa_in/out programs add latency, and as the
website said, you should not record using those programs.
I can guarantee that you'd need to sync them with SPDIF under Windows as
well as Linux, or you'll get clock drift between the cards.
alsa_out tools are build to compensate the clock drift.
There is this method:

If someone has some experience in using multiple cards, I won't mind a
pointer or two.
I've put up how I got it to work here: http://delta.brainiac.com/deltasync.html
I run 2 Delta 1010s synced up and it works well for me.
