Now everyone has stated some good quality speakers here, and there are a ton of others that have not been talked about at all... It seems like John Bailey is on a mission for some great quality speakers.. revealing/efficient, yet are we talking about a budget here.. ? John did you have a budget or did I miss that..
Everyone knows what I would recommend for a speaker, as I have bought it..
but I would really like to hear the Paradigm Sigs... but hey they are expensive

But I do truly love my studio's.. and I second the thought of adding into your budget some acoustical treatments... best money I have spent... (updated pics in my sig)
Now to the point.. you could do well by reading the link posted earlier by swerd...
http://members.aol.com/_ht_a/pjay99/guruscordell.htm all about quality amplification benefits/drawbacks.. the OP should consider this when buying power hungry revealing/(a bit less efficient) speakers...
Its also nice that you don't get the neverending assault from the B&W fanboys like over at AVS... but hey in my eyes, you really have to dump a boatload to get the sound from those... like the 803's (Bankroll)
Good luck in your hunt... don't give up til you find "THE ONE"
