I'm not quite sure where to put this; but I'm trying out a NAD M51 with my T1 & WA2. It seems to be a very complimentary DAC for the T1s. Treble is very detailed without any harshness. Bass might be slightly emphasized; but no "boominess". It's really a pleasant sounding combination that simply disappears into the music. I'm connected via USB, the drivers (and cheap cable) just work.
i ended up with a mytek 192 over the nad m51, but this was the second option i was thinking about. i bet it must be really good!!
