Comparison of $11,000 - $15,000 reference speakers

Looking for some feedback on speakers in the $11,000-$15,000 range used (pre-listen seems like an appropriate term if selling with a mercedes). The current rig consists of the Aero Capitole MKll CD Player, Jeff Rowland 302 Amp, JR Synergy11i Pre and N802's. My short list of speaker upgrades are:
N800's (non-diamond)
Sonus Faber Amati's
Kharma CRM-3.2's
or if willining to spend a couple extra $$
Talon Firebirds
Has anyone spent any time listening to and or comparing these models?
How about recommendations on synery with my existing equiptment?
You forgot the Andra II used and the Andra III.
I own the IIs and they will stay in my musical
for a very long time.
You should also consider Avalon Eidolons, Vandersteen 5a (used set for sale on Agon right now) and Montana speakers(very Dynamic).
I'll second Sugarbrie's recommendation of the Devore Fidelity Silverback Reference. They replaced a pair of Vandersteen Fives in my system, and I couldn't be happier.
