John's a good guy and so is his analog guy, Nick. I have some similar components. System looks great! Where did you get the granite bases made and how did you account for their height when setting up the Quatro's rake angle?
Your system reminds me of one of mine...housed in an old fashioned but nice "entertainment system". We had ours built in when we built the house when 36 TV's were huge. Live and learn.
If you're interested, I have two systems posted in the virtual section.
