Thanks for your response.
I like the black look of the other Mac receivers but the silver 4100 would match my cdp better. It is a different Mac look, but still very attractive.
Thanks for your advice about Mac receivers. I do have 4 ohm speakers so I should consider the 4100 or 4200 receiver. I'm glad you commented on the FM portion of the receivers. This is very important to me, maybe even more than CDs.
I made an error, you probably realized. I called the silver piece or gear on the bottom shelf a stereo tech. Anyway, you figured it out. I think your idea of isolating the TT is a great idea.
Very cool system.
