Yeah, I found that out when I was looking with some interest at the Emotiva BPA-1 (I think) and going, hmm, if I get two, and bridge them... not so much.

BTW, I don't think I've told you guys that my next pre/pro and amp purchase will be separates.

My buddy and I did some testing at his house with a 25 year-old Sansui and a newer Pioneer integrated receiver. The Sansui sounded "better" at the same SPL. We put his digital storage scope and programmable signal generator on both and discovered the Sansui's transient response made the Pioneer look slouchy. Maybe it was the Sansui's relatively monstrous caps that resulted in the difference we saw.

I have been leaning that way myself but the cost compared to a 3808 or similar, is a bit higher and for me that might be too much.

I suppose you can always save a little longer.

Boy, 37 more replies. There's nothing new about this and it's been discussed here at least ten times in the past few years. True biamping(questionable benefit for home use)requires two amplifiers, as the term implies. An amplifier basically is a power supply section connected to one or more channels of output transistors, which serve as valves to add the required amount of voltage gain(typically about 29db, about a 30-fold increase)from the power supply. The receivers which have a supposed "biamping" feature(among them most or all of the present Denons), apparently as an advertising gimmick, have only one amplifier(one power supply feeding up to seven output channels)and can't "biamplify".

Again, the amplifier always has to feed from its power supply to both the high and low frequency sections of a speaker. Funneling the same power to the speaker through two channels of output transistors(one previously unused)rather than one can't double the available power or increase it to any other degree.

Enjoy the music, not the equipment.

There were some interesting things that came out of this today.

For low impedance speakers, the extra set of channels most likely makes a very audible difference. But, there are probably very few of those in the world.

The extra set of channels can also power another set of fronts. I'm not sure exactly what the application for that may be. But I've noticed that two sets of fronts sound more full.

Oh my, Mojo may soon convert and realize that better equipment (seperates) can sound better than cheap AVR's, they are not all created equal. \:\)
