I havent used any of these, but I would go for the Avalon through the Rosetta setup because it offers more flexibility when you want to experiment with pres, because like mics, the same one wont work for everything. Plus you can use the rosetta for other things as well, like being the front end to your cd burner, if you have one, to go direct to disc. If I'm not mistaken, it can also be used as a D/A. I've heard some great things about the Trak2 nevertheless.
