I've been researching around since I've been generally unsatisfied with the combination of the HD800 and my dac/amp setup (Gungnir, Mjolnir).....it just becomes too fatiguing too quick. That setup has been a blast to listen to though with my HE-6 and the LCD-3. Lately I'm finding time to sit down to listen more and have decided it's time to upgrade the solid state setup. I am heading toward the GS-X for the amp upgrade and am now looking between the 3 DACs from reviews that are deemed more musical without veiling the details....I'm mainly looking at the Metreum Octave, NAD m51, and the Perfect Wave MK2. I thought I was set from everything I read on the Perfect Wave until I read the thread carefully and saw all the hoopla about the Mk2 firmwares sounding significantly different and also that a MK2 sounds inferior a MK2 upgraded from a MK1.....I've been a NAD fan for awhile since one of my theater setups is a mixture of NAD and PSB and I know their equipment is always very musical.
It's a good problem to have, but I was wondering if I could get more feedback from guys who's perhaps heard them all or 2/3 and give me some pointers for the decision. I appreciate the time and help in advance.
