Pete,
What type of music do you listen too, normally. Also I value your oppinion in these matters and would love to hear your system. Just curious, did you audition the Proceed AVP before buying the Lexicon ? I will concede after many more hours of listening that I can't decide what I like better, stereo surround or stereo in my set up right now, but again I'm going by memory because as I have said I don't have ML for surround right now but remember how good it was before. Also, I know what it is I liked about my old system, I sat 12' away from each speaker and I think this is one of the most important aspects to a correctly set up 5.1 system. Most systems (5.1)I have listened to don't have them hooked up this way because of room/show room constraints. Yah I know the processors take this into account when you set your speaker distances, but it is just not the same. I guess what I'm trying to say is the room treatments and dimensions are so often overlooked in this hobby, instead people are spending money on cables and wires, which help don't get me wrong, but do very little in comparison to having spent your time,money and energy in building the right room. Anyway, I too, am planning on the ML cls's bi-amped for the front putting the Aerius's back in the rear.
Thank-you Pete, and everyone for their continued input.
