well I get to answer my own question because I just got an old Sansui 7000 receiver raed at 70W/ch at 8ohms. I have not had a chance to do a straight AB test. My panasonic XR system is hooked up to Mirage OM 10 speakers and the DVD player is connected with an HDMI cable to the receiver and HD TV and the TV is connected with a toss link to the panny receiver. The panny playing CD's uses the DVD player as a transport with the HDMI cable and the panny is the direct DAC to the speakers. The sound is crystal clear - no noise very flat neutral sounding maybe a little bright.
The sansui I have connected to some Mission 700 bookshelve speakers and the sound is warmer - kind of like a tube amplifier. I was mainly listening to the tuner - a good receptiong npr station. the gist is more warm/tube slight enhanced bass sound for the sansui and crystal clear / neutral/bright for the panny. I guess they are apples and oranges.
