well is it possible you could tell me the name of the yamaha brand? because i'm going to get a new piano for christmas and i wanna look at one with that particular sound.
They don't mention which one it is. For drummers, they'll say "Ludwig Drums" and leave it at that. It's no help, ha ha!
The important thing to remember is that when you're listening to a finished record, you're not hearing the pure sound of ANY instrument. It's the sound of the room, the mic, the preamp, the mixing board, EQ, compression, etc......and that doesn't take mastering into account.
I had a Yamaha upright for years(my dad has it now) and they are made amazingly consistently. I'm prejudiced, though: my favorite drumset is Yamaha, as well.
My suggestion, if you have thousands to spend, is to get out there and play as many different brands as possible. There's so many breathtakingly good ones out there! But there is something about Yamaha. They're a company that seems to make almost everything crazy good.
