What Instrument would you listen to?

Human voice. Spoken, sung (individually and in choir) and male and female variants.

whatever you are most familiar with. Piano is very revealing of flaws.

I agree in this scenerio the piano is a good choice. But take it a step further, which recording?

Nothing is more important than timbre. That's the thing no system gets accurate enough to be considered LIVE.
Cheers

I feel that guitar comes closer, better, to a variety of instruments, voice included than any other that I am familiar with. It can have a percussive quality to it, a voice quality to it, it can carry a rhythmic quality or foundation of a piece. It is an instrument that speaks in a variety of ways to to me. For some reason colors come to my mind when I listen to music and for me the guitar creates more colors than any other accoustic instrument that I know of.
