It's very easy to respond Steinway in a thread like this without even thinking. Having been through a recent grand piano buying experience I can tell you there are lots of sub par Steinways out there. The variability from one to the next seems to be greater for Steinway than any other manufacturer. When Steinway makes a great piano it's a fantastic instrument, but there are lots of Steinway Ds that are subpar. Steinway spins this as each instrument has its unique voice so pick what appeals most to you.
I've played Mason and Hamlins, Bosendorfers, Schimmels, Estonias, Petroffs, Seiler, Suaters and Yamahas that were fine instruments. The instrument I like to play on the most is the Estonia 190 I own, It plays and sounds wonderful and it's in my living room.
