Seems to me that too many people are far too concerned with the badge on the front. I dont know mant people that evn use the surround modes on their amps. The only surround mode I use is 7 channel stereo just so the other speakers dont feel left out when I play music. One of my setups uses a Yamaha amp but only for the processing side. It is hooked up to a bunch of Perreaux power amps but only because the power section on the Yamaha aint big enough. When I have played this system to people, the only reaction that I get is "Holy F%$#"! Music or film. That is the only reaction that I need. It is pretty easy to fix a bad room with a bunch of heavy drapes. Your freinds wont care much if the left front is 4 degrees out of phase with the right. It seems to me that you like the sound of your L100's so go with it but you may prefer somthing with a bit more kit for the mains. L150's or L220's dont have a much bigger footprint and the do come up from time to time. You dont really need a sub with them either. The JBL studio monitors are worth a look as well but the occupy a lot of real estate. The JBL array series are worth a look. They create huge impact before you eevn turn them on!
