OK, now it's very clear : M-Audio Firewire 410 is not for Mac users. After the Powerbook 867, I have just tested it on a pretty modest PC configuration (P4 1,7 with 133 mhz motherboard, RAM 256 MB, Sound Blaster Audigy for the Firewire interface) and the performances are WAY BETTER than on the Mac. At the very same settings (128 samples, 48 khz), the difference between LAW 5.5.1 and LAM 6.2.1 is enormous. Had no time to measure the exact latency (would estimate it to something like 4 ms) but you can monitor a guitar with effects without frustration. Of course LAW's ASIO implementation has never been very good, so I guess other PC audio apps can even perform better with the Firewire 410. This confirms that there is hope for big improvements on the Mac side. But once again, LAM users : don't buy this product before it has better drivers. Yann Le Bihan
