Yeah, I'm a big fan -- I own two (sort of -- one was home-modified by its previous owner, and currently is not working). I've only heard their entry level DAC (the Link DAC III), but I'm very fond of it. Combination of the Rega Planet or the X-RAYv3 as a transport was excellent, so it's not as good about jitter rejection as they claim (I.E. it prefers a low-jitter transport as a source).
Justin also owns (or owned) an older Platinum. I'll let him give his opinions, though. My opinions of it at a few meets was that it was excellent, but that's all I remember -- I don't remember if it fell in the "smoov" camp or in the accurate camp. IIRC, it had just a nice straightforward no-muss-no-fuss type of delivery.
