Superb Service
Oppo has repaired an old unit for shipping costs only for me. 
Know of a "Dirt Cheap" tweak?
Putting digital and power on two seperate ac circuits makes a difference. 
I can't play a recording all the way through
Try playing the concept albums of yesteryear. 
Anyone heard about

Emotiva Amps and Processor for Home Theater?

Any DIY noise harvesters?

Using Professional Amps On Home Theater Speakers
I use Alesis RA500 with MMG's. Very happy and no fan. The Crown K2 is supposed to be even better.
