"What's The Best Value Speaker In $5k-$10k Range?"

Eggleston Andra-II go on sale for $7K-$10K and having owned them they are
both world class and truly full-range. I never played my pair super loud but
they can be used that way if you're one of the Krazy people out there.

B&W 802 Diamonds are also pretty great by most accounts.

Something by Sonus Faber would make music (Amati Homage).

Aerial Acoustics makes some terrific speakers (7T).
Revel speakers are highly regarded.
needless to say you want a very clean amplifier with 100 honest to goodness watts per channel to mate with a very good quality speaker system.

Verity Audio Parsifal Encore/Ovations. Of course this is just my opinion. I'm sure you will get as many different suggestions as there are speakers in this price range. :)

Add Revel Salon 2 to your list.

I would have to say Vapor Audio's Joule, the components alone are worth 2 or 3 times as much as the components in some other speakers in this price range, RAAL, and two custom audiotech woofers. I have heard it at a few audio shows and it has blown me away every time. I think I have seen the same audiotech midrange in some 50k plus models from other larger companies. I have heard the B&W diamonds a few times as well, as far as build quality and fit and finish they are pretty hard to beat and they have a pretty phenomenal sound, but for pure sonic bliss, I've gotta give the edge to the Joules.

It looks like the amp you have in there is more built for home theater than music, but it should be plenty of power 5x160W.

I have owned the Talon-X Series 2 since 2003, and without a doubt, these transducers deliver. Considering what they retailed for and what they now resale for on the used market,I cannot see how anyone could be disappointed from the money to performance perspective. A gem indeed...
