Sutts: My favorite DAC has always been the Audio Logic, which I've owned starting in prototype form since 1994 or so and have now in its 2400 version. It has one of the bigger power supplies, outboard, around for a DAC, goes plenty deep in my setup (I get usable bass in the 18-22 hz region with my speakers, and it delivers the goods), although there may be some Krell products that go deeper, and it is the most "alive" DAC I've heard out there in terms of a natural presentation, soundstaging, etc. Tubed, of course. For the used prices being asked, I'd call it a bargain. Haven't heard it with a TEAC DAC (only my Forsell and the CEC), so not sure how it would go with it, but I wouldn't expect any gross mismatch.
The Audio Notes are supposed to be exceptionally musical; I haven't heard them except for the kit version of the cheapest model, which I wouldn't trade my DAC for but for its price was astonishingly good sounding, I'd imagine their pricier units would sound great. Their gear seems to be designed for the person who wants to get off the equipment merry-go-round and listen to the music, like the Jadis components. I'd put the Audio Logic in that category too, but I admit to being prejudiced on this one. There's a lot of Audio Note owners on this forum who I'm sure can help you more.
