Avalon Eidolon VS the Eidolon Diamonds

I think both speakers have the same extension but find the Diamonds to have a much more articulate bass. In fact, when I moved from the Eidolons to the Diamonds my room required less bass treatment.

I too upgraded and I think the Diamonds sound much more dynamic and transparent along with superior bass definition. Coupled with Phil's comments of which I agree wholeheartedly, the net result is that the Diamonds are a much better loudspeaker (than the Eidolons), and at their price point they should be. I actually think the Diamonds offer a great value among other high end designs, which some may view as an outrageous statement for a retail price of $32K in a standard finish.
