"I put a NAD C162 pre-amp into this system (not my main system). It's my back-up pre-amp. The NAD is full sounding with good bass."
Did you leave the SP-9MKIII powered on all the time? If you did not leave it powered on you never heard it. So now you think the OP should dump his Audio Research preamp and get an NAD?
BTW, AR is Acoustic Research.
