I recently purchased a Sony receiver (Model STR-DE475), and was very unhappy with it. Any of you out there own this receiver? I found the volume level to be extremely weak. I had to turn the darn thing up to near max. to get it to the desired volume level, which I deemed to be ridiculous. And when using headphones with this unit, the volume is even worse! It has to go past max., and it's still too low! Anybody have similar problems with Sony (or other) receivers? Thanks.
