Piano that sounds like a piano

Sugarbrie...Exactly the point. Piano is an excellent test, but you must have a superb recording to start with.

Need more input.

Try Keith Jarrett, 'The Koln Concerts' perennial favorite of mine..

While in the local audio store the owner was playing a BIS CD of Lera Auerbach (BIS-CD-1242) which really impressed me (for what that's worth) with the naturalness of the piano. There's also some wonderful violin virtuosity demonstrated too. I haven't bought the CD yet but I think it will be a candidate for reference status. I believe there was a review of the CD in the November (?) issue of Sterophile.

My test track is Irmin Schmidt "Filmmusic Vol 3&4" -- "Aller Tage Abend Waltzer"
a unique blend of strong forte large octave notes and sonds transfer from mezzo piano to forte.
Becides that it's a unique piece of a great composer and piano genius of the 21st century.
