Hmmm. Why does the Quote box not work?

>> In an ideal world they should all sound the same and not "colour" the sound in any way<<

I agree. If I want to colour the music, I can do that. I shouldn't need special effects in order for the sound to be reproduced. I have an old Pioneer AVR, a VSX5300. It was a nice unit, very early Surround Sound. So early in fact, it doesn't even have a powered centre output, so one either needs a powered centre or an amp. I decided to get a non-powered speaker and use a Rockford Fosgate single channel 50W amp to power it and it sounded pretty good. If I wanted better or more prominent dialogue, I could adjust the gain on the centre amp separately and all was well. The sub had to be [self] powered off one of the front channels because there was no sub output either.
