I have my 2 channel Stereo and Home theater seperated and I'm using a pair of the 3 channel amp Parasound HCA-2003A and it just makes my Monitor Audio Silver Series Speakers Sing.Like you I'm also using the B&K ref 30 for processing.
If I'm to buy a multi channel amp now I would go with the 7 channels amps as most of the new sound formats in home theater needs 7.1 channels. Sorry to add to your confusion.
