The biamp ingredients I'm considering are a Conrad Johnson gat2, CJ art150 150 watt per chanel stereo amplifier, mcintosh mc611 600 Watt monos, and b&w 802 d3.
I like the idea of what Mcintosh has recently done with the combo ss/tube mono amplifiers. Although the MC 901 they offer, while costly, is too damn big, and probably generates a ton of heat. Basically it's a mono with 600 W solid state combined with a 300 W tube amp. I think the 300 W tube for mid range and tweeters is a bit of an overkill. And I already have their 600 W Monos.
