Hi,
I have owned Vandersteen, Totem, Meadowlark, Spendor, Reference 3A and Living Voice. The latter 3 do a very good job w/ piano, but the best I have heard with piano were Harbeths (with class A Pass amps) and Quads (with VAC gear). Unfortunately, the Harbeths didn't light my fire othewise, and the new Quads too $$$.
TH
