Avalon Idea vs Ascendant II


My target speaker is either Avalon Idea or Ascendant II, I’ve a small listening area and I think these speakers are suitable for me. My question is how you compare the sound quality of Idea and Ascendant II?
Or both speakers sound very same? Unfortunately my local dealer don’t have both speakers together at this moment, but I have test Idea, very impressive and I love very much. And the dealer told me although both speakers are using same type of drive, almost same design, but Idea’s Crossover are new deign by Avalon, it has better sound than Ascendant II (more transparency). And Ascendant II is almost 15 news old, Idea should be a better choice.

BTW, Idea is about USD2060 cheaper than Ascendant II in my region.

I wanted to demo the Idea but since the dealership did not have it in store we listened to the Ascendant and Indra to get a feel for the house sound.

I've been told that the Idea has a tonal balance with a more robust bass foundation. I was recommended the Idea over Ascendant for my music tastes - electronica and classic rock. It's a newer design as well.
I would question your dealers description since the tweeters are different.

I would email or call Avalon for a more distinct description of their differences in relation to your room size. With Avalon any increase in cost is indicative of higher quality parts.

IMO, I'd be lurking the used market for some Eidolons.
Thank you very much of your opinion! I only listen to Jazz music, mainly contemporary Jazz and some Brazilian Jazz (Bossa Nova), like this:

I hope Idea is the right choice
