Big, big room -- which 10-20k speakers?


I just moved into a house in which my listening room will be about 35 x 35 with 17-foot ceilings, with double-story double-pane glass windows on two sides. I will be running a Luxman 509u intergrated amp, a Sony XA777ES, and a Luxman PD371 with a Miyajima Shilabe. Cables are a mix of old Nordost Valhala and newer Kubala-Sosna Emotion. I know it all seems fragmented but I just moved back to the US after a decade living in Tokyo so these are bits and pieces assembled over there.

I am considering a variety of used speakers that can be purchased for 10-20k, namely the Revel Ultima Salons 2s, Rockport Mira Grand II, Aerial Accoustics 20T (I should mention I had 10Ts in the 90s and loved them) and YG Anat Studio II.

I'd love any thoughts on which speakers would perform best in the room given it's size and reflectivity, and given my rather odd electronics. Thanks very much for your advice!

I would recommend GR Research LS-9 or Super V's. Combine either of these with four servo subs and you could easily fill that room and fill it very well.
I hope you guys are listening to Ralph (Atmasphere). His comments are exactly correct and can only be stated with such confidence when a person has lived with a good system in a large room. The comment about shouting is a common one with my wife and me, as the sound is so relaxed and natural. Our home is quite open from room to room in the public areas, and the Great Room spills into another 3 rooms which are again in the 30x30 range. While wandering through an adjacent room I sometimes stop in my tracks, marvelling at what sounds like live musicians playing in the Great Room, at natural levels. Yet another example of knowing when the system is 'right'. And, yes, I do attend live musical performances with sporadic regularity.
Consider the Von Schweikert VR-44s or vr 35s.

You could look used and get a pair of VR-5s.

All of the above are simply stunning speakers.
A little known speaker that would fill the room with great sound is the old Pro Ac Studio towers circa 1988. They were 5k new back then and you can probably get a good deal if you find a pair. The are efficient, play loud without distortion and need a large room to sound their best.
