Kodiak, thanks! Haha yea I had to give up the M5s to help pay the nut on the 660s, great to be able to get a overly fair value in the trade up program. Now need to sell the Bryston to get some new QS10s! Although it's currently powering L/R on the HT set up because, why not? haha.

Mojo, You're sure right! I was very nervous since there was very little written or reviewed on the 660s, glad to be extremely satisfied and be able to get some opinions out there. That Carmel walnut is perfect match for up north. Hit them with a healthy amount of Pledge last weekend and really made em shine and made the veneer noticeably richer. Very happy!

2X - I had an SVS SB1000 I bought for the 2.1 and it was good but wasn't amazing so I sent it back. The Rythmik is on a different planet. I got a great deal, but took abut 9hrs of driving haha. Can't say enough good stuff about it's performance, value for money is off the charts.
