Thanks, Confused. Very clear conclusion indeed.
Besides the ability to hear how the note/sound was made on the instrument (it can be quite startling!), did you notice any added warmth (more Class A type sound) or better timbre/harmonics? How about improved depth of soundstage?
As you say, the interesting debate in future may be whether a 200 owner should upgrade to a 220 or add a companion to make it a 400 (all things being equal, a 440 should be better than a 400, of course). The question is whether the 220 comes close to or, possibly, exceed the 400.
