Very nice system.
It is not easy to find a spot to put a piano, but have you
noticed that the strings vibrate when you play the stereo? You may not realize it when music is playing, but it is easy to identify the problem by shouting in the same room, the piano picks it up and the strings will ring. These sympathetic string vibrations add undesirable noise to reproduced sound. Some kind of soundproofing over the piano, such as a quilt, is probably about all one can do.
