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.
