3 channel tube amp for home theater?
"If I used a five channel amp, does the Home Theater Receiver get replaced with something like a Home Theater Preamp/Processor?" Yes, many with more coming next week at CES." If so, how do you output the proper signal voltage to the monoblocs from... 
How to diagnose the need for room treatment?

Useful tweaks for Oppo 980/DTC 9.8 for MC-SACD
Are you running the 980H via HDMI? If so, I doubt there are any useful tweaks. If not, you should.Kal
