I've had one for a few months. It has served as my master clock and digital router. On the plus side, I think it sounds great, very happy with the pres and A/D. It also has some fairly cool features buried inside. I don't think the fans are that noisy, but this thing runs HOT.
On the negative side, once you load it with 8DA and ADAT i/o, you've spent some serious cash relative to what's on the market. Luckily I bought mine second hand very inexpensively. But I bought and installed the upgrades myself.
The interface and workflow are atrocious. I fired up my old iMac and hooked it up to the Trak2 just to get better access to the command interface. Documentation is minimal, with almost no knowledge base on-line regarding any of the complex functions. I was actually thinking of writing up a web page with my findings since I plowed through it all myself.
I haven't used the Soft Saturate feature much, not sure I like the way it sounds. I have used Soft Limit on occasion while tracking drums. In short, IMO the Trak2 is a competent unit at an overblown price.
