Bridged Perreaux Amp question.
Just picked up a second Perreaux PMF 1150B, which is a 100 watt a channel Stereo Mosfet amplifier. The amp can be bridged with a switch in the back and according to the owners manual will thus put out 400 watts! Now, I know that my S/3100 will take most of the extra power, but, accoding to Perreaux I should "not operate this amplifier into loudspeakers whose nominal impedance is lower than 8 ohms when in the bridge mode." The S/3100 is rated as a 6 ohm speaker.
What would be my risk ? Would the amp or the speakers suffer ? Or, should I forget about it and run just one channel into each speaker, ala mono blocks ? Any comments would be much appreciated. I am really curious to hear what a difference either the extra wattage running in bridge mode, or running as mono blocks might make. I certainly don't need the extra power, but am always up for sonic improvements.
Thanks - Bernard

Of course, this assumes you are using identical amps, i.e. the pair of Perreauxs mentioned earlier.
I'd agree.

You cunning devil, run the Jadis on the top, you could either run one Perreaux on the L/F or two, so you have big fun infront of you.
You got me going so I (just for the hell of it ) I threw another length of wire at mine and Bi wired them, my Aragon Palladium 1K mono blocks have that provision, so I'll now go and have a listen with a cool libation
