Too long and maybe off topic response alert: I've been a musician forever and think it's sort of strange that most musicians don't become audio geeks, so in that sense they resemble actual people. Also, sound is a personal perception thing...my acoustic guitars sound different in my hands than in somebody elses (you can't even count electrics as a reference), and the "piano in the room" (I have one in my listening room) reference exists only relative to wherever you sit...I mic live pianos at jazz shows (lately gigantic Steinways) by sticking a great condensor mic facing the soundboard with the lid open...and nobody actually listens to a piano like that, unless they got stuck in it somehow (you often hear pounding from 'em if the lid's shut...usually well after the party ended). Is the reference a live instrument in an acoustically dead space? If so that is not good as it's creepy and lacks life, and a reverberant live setting isn't your house. I think opinions of musicians may be useless (except mine of course), and if it sounds good to you, it's good, because it doesn't sound exactly like that to anybody else. So the answers are yes and maybe.
