Passive bi-amping works ?


I can't figure out how passive bi-amping (as pointed out in my Martin-Logan manual)in either vertical or horizontal modes offers more sonic benefits than using a higher-powered amp(usually better quality)in bi-wiring mode. Please enlighten.

If my poweramp has 4 channels and can be bridged to 2 channels, in general should I used 4 channel to passive biamp or bridge them to 2 channels. I'm asking in term of better sound quality only.
Supakit; biamping with a 4 channel amp is probably breaking new ground. I have read that "sometimes" bridging channels does not improve music quality/character. Good Luck. Craig
Supakit, try it both ways and tell us which way sounds better. I'm betting on the bi-amping. Let your ears decide, but get a quality y-connector and why not put it at the end of your present interconnect (female to two male with enough length to reach the two inputs)?
Garfish, looking forward to your review. TWO upgraded DNA-2s? I have a severe case of amp envy.
I used passive bi-amping and it was a slight improvement. I would suggest you go that route with the idea of eventually going to an active cross-over which will be a HUGE improvement. At least that was my experience. Active cross-overs are relatively cheap.
