Gene has been saying recently that he believes most AVRs (Denon, Marantz, Yamaha, etc.),not just Yamaha, have issues (even when using external amps) if the volume is high enough because they don't have a "separate preamp mode" that separates the internal amps from the preamp section.
@PENG I would assume that in "ECO" mode, the power and voltage would drop even more than normal mode?
So if someone were going to use a 300W external power amp, I would assume they would not want to use ECO mode?
Or did I miss the lecture day on ECO mode?
