Bi-amping B&W 703's

Guess I should not have said mono mode.

The Electrocompaniet amp have a little button at the back that allows you to switch from stereo to mono, but I'm not sure if that's the same as bridging on other amps.

Considering that I'd need more speaker cable I'll probably leave it as is.

Thanks

That is briding the amps. I would try unbridged stereo operation 1 amp per speaker.

That should yield a nice improvement.

when you say unbridged stereo operation with 1 amp per speaker do you mean using only one channel of each amp per speaker.

When the amps are in the stereo setting I really would need only one amp for the pair of speakers. Maybe I misunderstand what you mean since this doesn't seem to make too much sense.

No- you would use both channels on each amp.

So you have both channels of amp 1 plugged into speaker 1. One channel on the high frequency terminals, the other on the low.

Same thing for speaker 2/ amp 2.

This is called vertical biamping and is typically adventageous because the amps power supply/toroid only needs to drive the low fequency drivers on one speaker.

Just remember to pull the jumpers off each speakers biwire terminals (high freq to low freq bridges) so you dont short out the amp.

Good luck- I really like the way the EC stuff sounds. It seems like a good match for B&W.

Thanks Robr45,

I thought that if only one channel from the preamp goes into an unbridged stereo amp I'd only get an output signal on one side of the amp (basically one side isn't used due to a lack of the signal).

Does that mean I'd have to split the preamp signal and feed it into both sides of the stereo amp?

Thanks
