Avalon Eidolon Diamond-Worth it?

Tom,

If you don't mind, I have a question for your regarding the differences between the regular Eidolon and the Diamond version. (Nick, I hope you don't mind my slightly hi-jacking your thread!)

The specifications for the regular Eidolon, (I assume it is the same as the new Eidolon Vision), state it goes down to 26 hz. (I'll be honest and state I really thought it only went down to about 30 hz, based upon listening to it). The specifications for the Diamond version states it goes down to 24 hz.

Question: Can you really tell the difference between the two as far as their bass response is concerned?
I ask, because the bass response on the regular version, while very good, was not great. (And it took a powerful amp (200+ wpc) to get to that level.) If the Diamond really does go down to 24, that would probably be sufficient for my needs.

I am looking for a more full range speaker than my Revel Studios, and the regular Eidolon had about the same bass response as my Studio.) The mid-range and the soundstaging/imaging on the Eidolons was always pretty spectacular (IMHO), so if the Diamonds can just give me that last bit of bass response, I would be interested in them.

Thanks for the help!

Well, since I noticed that there was a flurry of responses to this thread, I thought I would update my situation, and offer a quick review of the latest Avalon speaker that I had the opportunity to hear.

First off, I ended up buying the Eggleston Andra II speakers. These are a sealed enclosure design, with twin mounted isobaric 12" woofers, that sound incredible. (They are very transparent, like the Eidolons, but with more bass punch.) They also have the Dynaudio Isotar tweeter, which I like very much, as it seems very refined. (Much more refined that the metallic tweeters from my old Revel Studios.) I am very happy with them.

Second, I have heard the Avalon Isis speakers at a friend's house. Wow! Not much else needs to be said actually, as they were that good.
Now, to be honest, the room needed to have some (more) sonic treatments, (as it was a bit small for these magnificient speakers), so the sound was not absolutely perfect, but one could easily tell that these are speakers are about as close to perfect as one can get, (at least in a dynamic speaker design). They have a very refined treble response, the mid-range is very transparent, and the bass response is deep, quick and powerful. (The only caveat I had about them is that the soundstage is much taller than I am used to. But I think that is merely because of the limitations of the speakers that I am used to.)
