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

I would not overlook Coincident.

I know everyone is going to recommend their own speaker brand, but don't forget Daedalus. Lou's Ulysses speakers fill a vast room at RMAF, they look stunning and are ridiculously low in price + every year they get a "best of Show" report at RMAF. What's not to like?

dc10 audio "the instrument" but more $$$ perhaps the dealer in Denver or CT will give a big cut.

See all the suggestions your getting? BIG ROOM...BIG PROBLEMS!! I had one and moved to a smaller room and system. If it's all about moving air for dance music and the like, then just get JBL K's or something. To enjoy the subtelty and texture of the music, you will need magic in a room that size. A pair of Wilsom MAXX's maybe would do it?

Just some general thoughts on each of the five speakers you've mentioned:

a) Revel Salon 2s: I own these and am very familiar with them - see my virtual system for more info. Pros: soundstaging is outstanding - they disperse very well and so your sweet spot is expanded, a considerable asset if you seek to move about your large room. And certainly capable of filling your room. Also they are very neutral speakers that should do well in your glassy room. Cons: they are not very efficient and would quite likely require more power than what your Luxman would provide, especially in a room that size. A few have complained that they are lifeless, although I do not agree.

b) Wilson Sasha: Have heard these on several occasions. Pros: very nice in well-treated rooms. Excellent, propulsive mid-bass and very extended treble. "Front-row" sound if that is what you are looking for. A little easier to drive than the Salon 2s. Cons: not a paragon of neutrality. Humped in the bass and treble, and that latter quality may make them fatiguing in a glassy room. Don't soundstage as well as the Salon 2s, nor is dispersion as good. But they might have been my choice for a man cave.

c) Aerial 20T: have only heard once. Pros: good bass when properly fed (like the Salon 2s, they seem to need to feed). Very good midrange coherence. Cons: tweeter did not seem to disperse well, so restricted sweet spot.

d) YG Anat Studio II: have not heard. Plenty of reviews of them both from publications (which seem to like them) and show attendees (mixed bag, some say they are grainy and/or lifeless while others think they are neutral and/or revealing).

e) Rockport Mira Grand II: have not heard (but I would like to). Not generally a D'Appolito configuration fan myself, but both pro reviews and blogs from people attending shows seem pretty uniformly positive.
