I bought a pair of Monitor 9 v.7's along with a Center 3 & love 'em. They play loud & clean & have a good soundstage. I'll pick up at least a pair of Surround 3's come boxing day. I'm running them with an old 10" JBL sub & a Paradigm DSP-3600 sub crossed over at 80hz.
Sound & Vision reviewed this setup (along with a DSP-3200 sub) & Daniel Kumin highly recommended them.
