Thanks Orest1 and Brauser, I will give the Mono-amp with bi-wiring a try when I have the $$$..:-). I'm thinking of the Pass Lab X600(used) and/or the Odyssey Mono Block(new). In the meantime, I'm currently vertically bi-amping two s200 with an S100 preamp driving the Sony SS-M9ED speakers. Will this setup sound better if I just use 1 amp in regular bi-amp mode?
