OK guys, I hear you. And I 'm sure few people have heard more K2600s than you, George. But with all due respect, I have to say that my engineering background is making it very difficult for me to understand how this is a hardware problem when I only hear this on SOME of the piano programs, and NO other programs. And it is not a screaming buzz; it is relatively subtle.......but clearly there if you listen carefully for it: cyclical, slowly decaying out over several seconds. It is just hard for me to see how a hardware problem would be triggered by only these specific programs.

So, I hesitate to open up the K2600, or to ship it off for repairs. My guess is if I ship it off, it will get a clean bill of health.....and I'll be out the risk of shipping and the wear and tear that goes with these wonderful conveyor belts.

So, I am hanging here in limbo. Slowly going nuts!!

OK, George, I can open it up, but I don't really know what to look for. You would ship it off and ask for a complete checkout by an authorized repair service?

Thanks,
Mike
