I listened to a couple of albums this evening, using three amps - a strapped Kaiju monoblock on each channel's woofers, and a single stereo Kaiju driving the tweeters for both channels. The bass definitely stays more controlled at higher listening levels. It's going to be fun trying all of the different possible combinations. Just takes some y splitters and extra cables, and a little bit of output transformer secondary rewiring.
@Aaron - sure, bring the EML meshies, would be fun to compare to the solids.
If I determine my mix to be acceptable I may demo a track or two that Jim Laurel recorded at Jacqui and Art's concert last month. We had some fun capturing the room sound by hanging a mic in the hallway downstairs. Worked pretty well.
