What would you use

Onhwy61, that would be a challenge. I seriously doubt I could even come close. But, in small scale music, I can do it alot of the time. I guess it comes from playing in a band, and always paying attention to the sound of everybody's instrument. Since I was the "techie", I got to do the recording and mixdowns, in addition to playing keys. When you do that, you get pretty familiar with the sound of the different instruments and effects units. Alot of times, I used to suggest the effects patches and stuff for the guitar player. Of course, he always told me that I was a keyboard player, and what do I know? You know how those guitar players are.

Twl, nothing was more irritating than having the piano player tell me to tune my guitar. Enjoy!

Marakanetz, if you're asking about which speakers would one use to distinguish between different pianos, I once gave a demo to a piano instructor and she could readily tell me what kind of piano was playing. We were listening to a pair of Sound Labs. Unfortunately, the piano instructor was a B&B guest rather than a customer, having taken the customary vow of poverty.

Another time I bought a disc of a local pianist (Seth Kaufman), then later heard him live. Now, I'm no piano expert, but it sounded to me like the same piano, so I after the performance I asked him if the recording had been made on the same piano. He said yes, and added that he'd had his piano shipped from New Orleans to Los Angeles for the recording session.

I'm not saying the Sound Labs are the only speaker that can differentiate between different pianos, but they are among those that can.

Another speaker that I think would have a good shot at pulling it off would be the Quad 57, especially stacked pairs.
