And going back to the subject, piano sound is one thing my Geek Out (1000) cannot reproduce in a convincing way, especially for the lack of harmonic vibrations coming from the gran codas. No faithful decay in long notes if you know what I mean.
I believe that would be from the low end bass distortion that gives the 1000 that fuller/warmer sound. You need precision and clarity as well as dynamic swing to render those harmonics.
I also agree that Steinways are a bit bright and on the analytical yet fun sound on the spectrum. Quick and playful. I talked to Tian Jiang whom I saw perform on a Yamaha awhile back and asked him what his preferred Piano was. He only said that he was Steinway contracted, lol. They do have impeccable quality.
