bi-amping with Mc352 and Mc2102

Larry,you may want to visit AudioKharma for some detailed advice on bi-amping with a Mac tube amp. Apparently you have to limit the frequency the amp sees at the imput level or the amp will experience heat and distortion. This can be done with an active or passive filter on the line input. Also in reference to input level matching, the MC275 has 2 line pots, one for each channel which should facilitate this, otherwise you will need a filter with level control (Marchand) or a filter and a line pot.

Hi Larry
I am biamping a pair of N801s with MC1000s and an MC2000. I love the way it sounds, the tube amp smooths out the highs and has a sweeter midrange than the solid state amps. By itself, the MC2000 just didn't have enough balls for the 801s. Although McIntosh told me over the phone that the amps would match output-wise, this was not the case and I have to pad down the input to the MC1000s a bit to tame over-heavy bass. I had a pair of in-line pads made for the job and they work well but am currently exploring equalizing the bass response in my living room, and am therefore able to control the bass level through my equalizer, eliminating the need for the pads.
All in all, I think the setup you suggest could sound great but you will in all probability need to match the amp levels somehow.

Thank you all for timely, info. I'll post my final decision in the weeks to come!!
