Weseixas, I agree, I think some of the Onkyo amps/receivers sound quite good, which is what prompted me to put it in the system in the first place and now I'm glad I did.
I also want to say that my slant is that the loudspeaker should be matched to the room first and then the proper amp to drive that speaker in its intended acoustic environment can be sought (based on the speaker load, sensitivity, and how loud the owner wants to play his/her music in the particular room).
