I've been very fond of my MOTU 828 interface since early 2000, when I used it to start work on The Most Distant Point Known
with Dave Fulton. It's been my primary audio interface since that time and I've used it with four different Apple computers, an iBook, a Powerbook, a G4 Powermac, and my new Mac Pro. It has always worked flawlessly and simply, no problems, no glitches, nothing to complain about.
In the past year, though, since I've upgraded to Mac OS X 10.4 (hate to think what would happen with 10.5), I've had increasing troubles with the interface getting "lost" and requiring multiple reboots before I can get the Mac Pro to "find" it again. It still seems to work OK with my older computers, but the Mac Pro is my main recording workstation now, so I'm about to change my primary audio interface for the first time in quite a while.
I just ordered one of these:
It's the Presonus Firestudio. Link here:http://www.presonus.com/firestudio.html
I considered several other options, and in fact almost bought a Focusrite Saffire Pro 26, and also considered an RME interface. Once I receive this item next week and set it up, I'll post a mini-review or evaluation here. I may also be selling my 828 here (though I wouldn't recommend it to anyone running the very newest Mac OS X version), depending on whether I just move it over to my G4, sitting 8 feet away. I'll definitely be selling one of my M-Audio Firewire Audiophile interfaces, since I was just using that for midi and supplemental monitoring on the Mac Pro. The new interface will replace both the 828 and the M-Audio device.
