Your thoughts on best audiophile speakers in $10,000 neighborhood?

You got a lot of good suggestions here — Revel F228be, Monitor Audio Gold, ProAc K series — all are great loudspeakers.

I just came back from a weekend of listening to my buddies new Sonus Faber Sonetto VIII. They’re very nice speakers; you can’t go wrong with them.

Two suggestions from above that you shouldn’t ignore; 1) Go to the Axpona show in Chicago this weekend to audition speakers, and 2) Don’t buy until you’ve had a chance to listen to the Borresen X speakers recommended by Audioman58. They’re a different type of sound than the Sonus Faber but, to my ears, they’re exquisite and a great deal.

I just purchased a similar speaker, the Scansonic MB6 B, designed by Michael Borresen. They’re similar to the Borresen X and also a very good value. I’m 100% satisfied with them. I believe the Scansonic MB5 B is right in your price range and they too are outstanding. 

Good luck with your search and let us know what you decide.

Pure Audio Project beats all!!!!

Used Magnepan 20.7i's can be had for less than $10K and if you have the proper room and amplification I suspect they will outperform the vast majority of speakers at many multiples of that price.

Heard the Borresen X-3's at Florida Hi Fi Expo........Many beautiful looking and beautiful sounding speakers there. .......But ONE speaker stood out for it's detail and soundstage and realism . The musicality of the Borresen X-3 along with their LOOKS was a game changer for me. Bought a pair in White with Black trim.....Absolutely Magnificent!  As mentioned above.....The ribbon technology they use in their $500,000 speakers trickles down to the $11,000 X-3's....Call Mike at Hi- Fi Loft in NYC or Next Level Hi Fi in the Chicago area before making your decision.

Sonus Faber Sonetto VIIIs are only $7000- you could go up to a Olympica Nova II for 10K. Sonus are "polite" warm speakers and not known for speed or detail. You could go to a Maggie 3.7i for 9K which seems to more closely match your listening preferences if I understand your post correctly (treasure detail transparency not warm) 

Your room is going to be a challenge- anti-rooms off the main room make for cave like echoes. You will need BIG speakers to fill that room.

Your amp is going to be the choke point. Old Nachs are cool but don't have the ability to reproduce the detail you indicate you are seeking.  You will need a tube amp to reveal the details in your vinyl that your speaker is capable of presenting. If you don't need to rock the docks and shake the lakes I'd look for a good used ARC Ref 160S. I have seen them for cheap lately as ARC is about to release the Ref 320M and well heeled ARC fans are trading up. 

Disclaimer:  My first good speakers were Maggie MG-1s which I bought new at Absolute Sound in Birmingham MI in 1977 with paper route money. Harry was an ARC dealer and my first exposure was to the Maggie/ARC matched stuff and I was blown away. 47 years later I still thrill at the ARC/Maggie pairing. I don' t own Maggies right now- I use Bryston Model Ts because like you I have a cavernous room to fill with sound and my set up is not for critical listening.
