Damn, that is the least positive topic I've ever seen about a Focsurite product. I've otherwise only heard good things about the little unit; maybe his is legitimately defective? I have a Pro 24, and my DI's max at about -16 with the gain at 0 using my BKP Painkiller. I usually set it to 4.5ish to get a good DI level. I assume the hardware is a bit different than on the USB, but the second poster said he had the same issues. Weird. Also, how the fuck does he expect to get such low latency? I get 1.9/3.9 according to Reaper, and I can track with amp sims just fine. Hell, I can track fine with double those numbers.
In any case, I'm curious about the Saffire 6, too. The newer Scarlett interfaces look a little bit better, but I've found the Saffire 6 for $160 on eBay. Idk how much they go for in Sweden, but I'm sure it's also a good amount cheaper than the Scarletts.
