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.

I've done it with B&W 802 with tubes on top and solid state on the bottom,yes it can be done passively,and it eases the demands on the amps too.Make sure the preamp has 2 amp outputs.
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.
