I have the MP-D2 MK3 and I'll repeat much of what has already been mentioned above. Organic and natural is a good place to begin. And I will add relaxed, detailed with loads of timbral integrity when film caps and tubes are replaced with high quality parts. Garry is a real gentleman and honors his customers with real world audiophile respect. I bought this instead of a Denafips Pontus because I could tweak it without having to breakout my soldering iron, I highly recommend you give this a listen before dropping thousands more on a hyped up audiophile (forums) DAC (s).
