Sure. Same goal, some research done. I'd avoid USB because of latency, but FireWire is great (low latency, large throughput, works with both Apple and IBM style machines). I like the ESI Quatafire (1/3 19"). Roland Edirol has a similar device that is slightly cheaper, but offers a restriction on how many channels you can use. (1/2 19") Then there is the RME Multiface that uses either PCI or PCMCIA, and is supposed to have superior quality at a superior price. (1/2 19") Finally, for the ultra high end (my dream card), there is the Apogee Ensemble FireWire that offers the famous Apogee D/A converters and four Apogee Pre-Amps. This is my dream card. (19") It is untested with linux. To go a bit lower in price, Echo offers the Indigo DJ with two stereo outputs and no inputs as a PCMCIA card. To run firewire cards on linux you need the FreeBob package, that has a seperate backend to Jack to be used instead of ALSA. Note all of this based on my research and is untested. Carlo
