I own a pair, so I am biased, but you can pick up a pair of Vienna Acoustics Mahlers for $4k-$5k used (retail is $9,800).
Here is a link to reviews of the Mahler. The Stereophile and Audio reviews are accurate. The Ultimate Audio review is too flattering (the speaker is not that good).

There are a gazillion other options at this price point, but the Mahlers are full range, image and soundstage very well, and sound excellent at both low levels and at incredibly high volume (each speaker has two 7" mid-woofers and two 10" woofers -- they can go really loud without distorting). They are efficient (90 db.), but need a quality amp and the right speaker cables (Kimber Select works great) to control the woofers. They have incredible bass and the wood finishes are of the highest quality (they are like fine furniture).
Good luck.
