I am not promoting anything I sell.
It's worth the half hour setup time/effort to audition my Ambiance/Mode Cancelling Array with
any pair of stand mount speakers:
http://jamesromeyn.com/home-audio-gear/ramca-romeyn-ambiancemode-cancelling-array/ This array provides acoustic benefits I've never heard before. It arrived from ground work by Dr. Floyd Toole, Richard Shahinian, Duke LeJeune, and others.
Stand mounts require subs, an indirect segue to the room treatment issue mentioned previously. We associate treatment with improved bass performance. I rather suggest, as a long term more effective solution, forgetting treatment to improve bass linearity in favor of the Distributed Sub Array philosophy (Geddes, Toole, Welti, LeJeune, etc). Member *Scotty* introduced me to the Double Bass Array. Though I've not auditioned the DBA it appears to offer all the acoustic benefits of DSA. DSA and DBA offer real audible benefits sorely lacking in every other bass philosophy regardless of cost and complexity. DBA done correctly may cost more and be more intrusive on the environment than DSA.
The combined Ambiance/Mode Cancelling Array + DSA define the state of the art for me anyway.
Regarding stand mount speakers: I auditioned the not yet released all-new Revel Performa3 M106 (circa $1700/pr MSRP) at 2012 CES. You'll not be immediately concerned with subs. IMO it can not be touched anywhere near its price. In fact, I'd say the next step up, if there is one worth considering, is in the $5k+ range ($5k/pr Canalis Anima CS and $8k/pr AudioMachina come immediately to mind). Last I heard several weeks ago, ETA delayed till approximately December. I can not more strongly recommend delaying purchase till they appear. Designer Kevin Voecks has a long and splendid history. Performa3 is another in a fast growing line of speakers employing waveguides to match tweeter and mid bass radiation patterns (Geddes, LeJeune, etc).
http://www.revelspeakers.com/News/Story/80 I think Ncore matches Levinson performance, which was stupendous in the CES demo, leaving nothing to be desired. I did not hear the slightly smaller/lower cost Performa3 M105 (5.25" midbass vs. 6.5") but it's worth considering, even more so if subs are in your long term future. Do not, I repeat, do not, confuse Performa3 with earlier Performa, with absolutely nothing common between the two.
My other favorite stand mount (not heard) is the just released $1500/pr KEF LS50 5.25", whose coaxial driver appears exactly like Blade's, one of my favorite all time speakers (Blade philosophy shares some bass-loading attributes with DSA).
The high end needs and benefits from small boutique designers/builders. But audiophiles sometimes miss the cost/benefit of huge companies with large engineering departments such as KEF and Revel (Harman).
