I'm seriously considering a reconfiguration of my HT to inlcude my Pioneer SX-850(circa 1977)receiver and looking for feedback as to what I can expect sonically (using my M3ti's). My current AVR is a Denon AVR-1906 and very much intrigued as to how the Pioneer will perform. Basically, this is just a quick post to see if this effort will be worth my while as this unit now sits in my son's room and he's already barking and pleading to let things alone. It's probably gonna take a good part of the day to do this task. BTW - my Pioneer is now running a pair of Sansui SX-5500X speakers (still sound excellent after all these years but lacks certainly in the midrange coherency compared to the M3ti's)...bought the same time as the receiver in Japan. So, if anyone can comment, much appreciated.
