Not included in your list, but have you considered the Hyperion 938s? They look similar to Watt/puppies. I recently bought them (wrote a review here recently) and find them to be great with all sorts of music including rock (I've listened to Richie Blackmore's Rainbow, Ozzy's Blizzard of Oz, Eagles, etc) and sound great with my tube gear, but your MF amp should really rock. They retail for $4k but usually you may be able to get 10-15% discount. Personally, I like the Hyps better than the Watt/puppies. Just my 2 cents. Check out hyperionsound.com for a dealer near you.
