It's good to be reminded of some of the bennies of living in such a densely populated metropolitan area. Whew! Them's some nice pianos!
Wolf, did you get to hear anyone play the pianos while you where there? I'm a bit surprised, because I would have expected the pianos to have affected the sound of an audio system in the immediate vicinity.
In searching for guitars, I have invariably noticed they sound better in the music store when the other nearby guitars are all vibrating in sympathy. The bigger the store the more guitars, the more guitars the better the sound. At least that was my experience.
