How about the PSB Synchrony One? You can find them used for $2K or so. They were listed by Stereophile in 2012 as a starred “Class A [Restricted Extreme LF] Loudspeaker Recommended Component,” along with speakers costing up to $80,000 in that category, and as a “Recommended Reference Component” by Soundstage Hi-Fi —again, in competition with vastly more expensive speakers. Summing up his review in Stereophile, John Atkinson wrote: “the Synchrony One offers surprisingly deep bass for a relatively small speaker; a neutral, uncolored midrange; smooth, grain-free highs; and superbly stable and accurate stereo imaging. It is also superbly finished and looks beautiful. Highly recommended. And when you consider the price [$4,500 a pair, and $5,500 a pair by the time they were listed as a “Class A Recommended Component"], very highly recommended.” SoundStage HiFi awarded the Synchrony One “Reviewer’s Choice” recognition when it was first released in 2008, then “Recommended Reference Component” status in 2012. The original review found the Synchrony One “among the most neutral speakers ever reviewed” that “sets a new standard for tonal accuracy, clarity and detail.” The follow-up review noted that the Synchrony One is “the least expensive speaker to ever be included in our list of Recommended Reference Components,” and that it measured (in the anechoic chamber of Canada’s National Research Council) lower levels of distortion “than any speaker at any price we’d measured up till then.” The review concludes “it’s important to realize that the Synchrony One isn’t being recognized as an RRC for the performance it offers at the price [$5,500 a pair]; rather, it’s a reference-caliber speaker that compares with top-class speakers at any price.” You can find these and other glowing reviews yourself with a simple Google search.

I bought a pair to replace my beloved but ailing Scientific Fidelity Teslas--but then found a guy in PA who was able to repair the Tesla drivers. I'd be willing to sell my PSBs. Got the boxes, manual, spikes and port plugs. PM me if interested.

I've heard the Spendor A series speakers and thought they sounded very nice for the money.

Ohm Walsh the best, but also always liked the old Totems, aka Arro, Forest, etc., for something more conventional but not obtrusive, especially with current used prices. PSB Synchrony also very good.

Those top of the line triton speakers are thin, and sound great. 
 Golden ear I think. 

While I have not heard them, I might also suggest the KEF Blade 2, used. I have owned the original LS50s and currently use the Metas in my stereo rig. The uni-q driver excels at horizontal / vertical dispersion and driver integration, which translates to a large sweet spot and beautiful sound throughout the whole room. Your 2ohm taps might work well with the Blades? There's no shortage of positive reviews, so I'll leave it at that.
