Avalon: are new models quite better than older ?

Luca, as I mentioned at the outset of your thread, I experience no slow or muddy bass on Eidolons here. Here the bass on the Eidolons is extremely tight, well defined and agile. But the Diamonds are better defined still, so perhaps the Radians are as well. But this is a matter of subtle degree of refinement, not the gross level of difference you seem to be describing. If you are using the same amplifier with both the Eidolons and the Radians, could it be that the amplifier is not as good a match to the Eidolons as it is to the Radians?

Dear Rushton, the amps are the same: Pass X600, well know for their great control on speakers drivers, so I doubt that could be a problem due to amps. Anyway, thanks again.

I believe that you will find the Ascent mk2 to be the speaker that does it all for you(based on your comments).This was Avalons premier product originally and they have not bettered it in any of their three way designs regardless of ad copy or industry hype.They were a sealed enclosure(more articulate bass and midbass).They were a very easy load on an amp(lowering how hard your amp has to work,meaning lower distortion).They came with a seperate external crossover(would you want a crossover in a potentially resonant enclosure or external?).They had significantly more mass in the enclosure and had unbelieveably high resolution in the vital upper mid to high freq.They were discintinued due to wife acceptance factor(4 cabinets,including crossovers)and the need for Avolon to distribute a more compact design.These speakers really have to be heard to be believed.They are occassionally available used at about 5-7k and are a steal.I have heard them on numerous occassions in various Manhattan loft set ups and always felt that this was Avalons towering achievement.Don't take my word for it ,try to hear a pair.Avalon once had indicated to me that they had received one pair back on trade in and "had forgotten just how good the sound".YOU can believe me or not,but I'm not making this up.

Dear Sirspeedy, good to hear from you again ! Just now I'm dealing for a pair of Ascents... I'll let you know soon. Thank you, Luca.
