Cambridge audio for two channel

I was looking at the cambridge audio 6.1 reciever today. I will be using it for 5.1 theater but was wondering how the two channel performance was? Any thoughts or experience with this unit?
I know their new 640C CD player turned a few heads. Dual Wolfsen 24bit/192khz DAC's. Priced around 700CDN
The series 2 is excellent with more control over the setup you can usually exceed its two channel performance by using DPLII. On two channel CD the results are adequate but the upgraded multi-channel facilities elevate CD playback to a higher level using on board DAC's and surround in playback, especially you're using speakers near the $500-$700/pr range. A rare over-achiever for the money.
