We sell the MA3, however not the Playback Designs. The Meitner is extremely smooth, very detailed and has a wide soundstage. The upconvert to DSD, the fullness of the sound, and instrument separation are top notch. Very good build quality, volume control, and a nice remote. It helps to pair with a system that is very revealing and detailed already - think beryllium tweeters, Focal, Perlisten, Von Schweikert, or other brands with similar high frequency signatures.
Hope that helps to describe what you get with the MA3.
