CI 200 digital amps (auditioned several), got that digital amp junk out of my system and couldn't find what everybody was talking about!

Theta Dreadnaught II (big, typical 5-channel amp weaknesses)
BAT VK-60 factory monoblocks - my winter amps, still own and love
Proceed BPA 3 (used for center channel and rears for my very low demanding HT needs for which it does a fine job)
It has been 12 months now since I got back into this hobby and I have been fortunate enough to try a couple of other amps mixed in with these that I did not own/purchase but borrowed from others. I feel pretty content with my system and actually like the fact that I have to change amps when the seasons change as it gives me half the year to enjoy tubes and half the year to enjoy SS.
I have learned that even after buying some of the highest rated 5-channel amps (Theta Dreadnaught II for example) and having a couple of others, that I have come to the conclussion that a 5-channel amp cannot perform at the same level as a dedicated 2-channel or mono amp can (of relatively similar price points). I have also come to the conclussion that I prefer a stand alone HT processor and for my needs one that is a couple of years old (ie. about 10-20% of its new price, as my demands for HT are low) combined with a good stereo pre-amp that offers either unity gain or an HT pass through.
