Since the 950-7100 combo or any other similar has a freq. response of 20-20K +/- a fraction of a dB, I wonder why you think that simply changing the electronics is going to reduce room effects? I have had all sorts of gear in my setup over the years, and I can say that in my experience there will be no significant difference. That is unless you clip the amp, also some processing can differ. Otherwise, I defy anyone to simply change the electronics on a 2-ch. setup and immediately tell the difference. OK, bottleheads need not apply
