For anyone who read my post above about comparing the Crown 1502's to the Schiit Vidar in my system, it's not even close. It's actually surprising how much better the Vidar sounds.
Now, that said, the configuration that I've found that sounds the most fun is to bridge the Crown amps for the low end on each side and run the Vidar amp to the upper end. That way I get everything that's great about the Vidar amp with the basically unlimited power of the Crown amps for the bass.
If I listen to Erykah Badu with just the Vidar powering both speakers (with a jumper,) the low end isn't involving enough to really be fun. I decided to try the Crown amps bridged and this is the fun I'm looking for. As a bonus, I get level control for the bottom end through the amps.
Is this the most high end configuration possible for these speakers? No way. But it's the most fun with what I have here in front of me. The only other thing I want to try is driving the bass with the Yamaha M-85 I was using, but I don't actually have speaker wires to try that right now. I have 3' Transparent The Wall speaker wires that I was using in my bedroom system (40" TV and CDM2's on my dresser.)
I bought a bunch of Rockwool Safe N Sound on sale yesterday at Home Depot for $14/bag. I'm going to make a bunch of sound absorption in the next week or so and see if that improves things further.
I need to write to Anticable and see if I can modify my speaker cable order still or if it's too late. I guess if they offer a trial/return policy then I can return them before they ship them. I'm still not 100% sure what the best cable configuration is. I was most surprised that I seem to prefer my Straghtwire interconnects to the Tranparent Music Link Plus for the high end.
I think my conclusion for the OP, as it pertains to this thread, is that it's way more complicated than someone in a forum on the Internet being able to just say "do this." Maybe you'd love the Pass Labs recommended above in mono-block form, or maybe a couple of Crown amps like I have ($350/each) bridged for the bottom end would work for you, too, and leave you $2200 for a very sweet amp for the top. My friend in college had Legacy speakers. I'm sure they could have used a lot of power.
