Since the Dunlavys, Amatis, Watts, and Eidolons have different presentations, ranging from laid back musical (Amati, then Eidolon) to potentially detailed and agressive (Watts, depending on system), I would choose the speaker characteristics I wanted first. I believe the Eidolon has better bass than the old SC4's, but the bass is less well integrated (and powerful) than the best. It's imaging is superb, as is the refinement, speed, and tonal characteristic. The Watts are, IMO, the most dynamic of the four.
Eidolons are reasonably good with lower powered amps but improve markedly with higher power - you will likely find yourself looking for trade-ins eventually on the CJ's to higher powered tube amps or solid state monos. Check the Eidolon reviews on AudioReview.com and in old A'gon threads, there were some earlier good comments on amp and power matching from a wide range of users & tastes.
