I second the earlier mentions of the Legacy Whisper and Revel Salon 2's. I would think you would be struggling however to find a pair of Magico S3's for under $10k any time soon. Infinity IRS Beta's can be found in good shape for under $10k used, but their age and lack of replacement parts precludes me from recommending them.
Personally I vote for TSW Apogee Duetta Signatures which offer remarkable sound for the money, whilst in a smaller room or where less critical speaker placement is required, I vote for the [url=http://app.audiogon.com/listings/full-range-marten-design-coltrane-alto-low-hours-excellent-condition-2014-12-13-speakers-92868-orange-ca]Marten Coltrane Alto's[/url] on A'gon at the moment. They were $22k speakers back in 2004, and even at that price Marten weren't really making any money on them due to their extremely complex design and carbon/kevlar monocoque construction.
