I used to think he was trying to intimidate us younger aspirants with scare stroies. And then his pianos were such dreams. But I do know in the later years he flew to Braunschweig, and hob-nobbed with Herr G (in German of course) and chose which he wanted. So do you think they choose for you... "Dieser ist gut genug für das verrückt American guy who RENTS them?" Regarding your " zinging at the capo bar, " I thought this was interesting from the Mechanical Music Digest list, "[ "Dithering" adds a weak wide-band noise (a "hiss") to the analog [ input signal before it is converted to discrete values by the [ analog-to-digital converter (ADC). The hiss is inaudible, but it [ helps the fidelity by reducing conversion jitter." Robbie Rhodes. So perhaps your D's are dithering? ? (I hope they didn't charge you extra.....) Now how do you feel ?
