"Absolute best" used speaker for $8-10K

A few recommendations (very nice system, by the way):

Zu Definitions. How can you turn down a 60-day trial?
Tyler Woodmeres. Used or demo (call Ty) will be in your budget, and they will fill that room.
Silverline Bolero. Made for the music you like, and work well with Pass amps. Refined, resolving, they sound 'right'.
EgglestonWorks Andra II. Maybe $500 over your budget, amazing speakers.

Best of luck.

Boa2, I'm contemplating on the Andra II. From the Stereophile review it look like one of those rare one that does everthing just right.
Any could share some info. on this speaker with me. Thanks again.

Andra's can be difficult to place, but sound amazing when positioned well.

Ny suggestion would be Legacy Whispers. Very open, revealing and true to the source. A "you are there" speaker, if that is important to you.

I would like to add: Martin Logan Summits or Wilson Sophia or BW 802D.
