I had 2 Layla 20's and sold them to buy a MOTU 24i and a 2408. The shit never did work right even tweekin' the hell out of my PC. So I just sold them and went back to a Layla 24 and a Layla EXP. I 'undid' all the tweeks and put my computer back to the way it was, put in the new PCI card, installed the most current driver and everything works great. Plus, I've got lower latencies than ever with the MOTU stuff even with all the tweekin'. The Layla clock is much more stable than the MOTU ever was and the audio sounds noticeably better because of it.
