Wow, how time flies by. In weeks since I posted this, I've been on international travel, moved apartments, and am only just starting to feel settled in. Anyways, I wanted to hop in here so that I could respond to all of these fantastic suggestions and keep this from becoming another "dead thread."
First off I'll say that while I'm sure Tektons sound incredible, there is literally zero percent chance I can sneak those into my living room past my girlfriend. I know, tale as old as time, but its very valid.
Second, and this is where the meat of my post is, thanks to @g2the2nd's suggestion, I looked into Volti audio and learned that Greg's workshop is not far from my house! I wound up swinging by to demo a pair of his Razz speakers and wound up staying for a little under 4 hours. One word is: WOW. I'll come out and admit it, I was totally mistaken about horn speakers. From my earlier Klipsch experience, I was expecting, as my post alludes to, a "cupped hand" sound in the upper midrange. Intuitively I guess this makes sense since every horn we're used to hearing in "normal" life sounds like this. Megaphones, announcement speakers, cheap PA systems, a horn shape should sound horn-like, right?
Well, Greg's speakers left me with egg on my face and my jaw on the floor. Not only did they not exhibit any of the shoutiness that I was expecting, but they presented some of the most lifelike and effortless midrange I have ever heard in a speaker. I think effortless is probably the best descriptor I could use to describe both the Razz and Lucera, which I wound up spending a couple hours with as well. This quality was especially apparent at lower volumes and during off-axis listening, where the speakers' characters continued to shine through. With the volume cranked, neither speaker showed any signs of congestion or confusion, though the Lucera's bass loaded the room better than the Razz seemed to. Imaging and soundstage were truly difficult to describe, with instruments actually jumping out from behind the listening position. This was the first time I have ever experienced this effect from a speaker in my life and it was impressive to say the least.
Honestly, I'm now pining after a pair of the Luceras after this demo and it easily sticks in my mind as one of the top hi-fi experiences I've ever had, saying nothing of Greg's hospitality, which was top notch. If nothing else was achieved, I at least have a greatly changed perception of what a well-tuned horn speaker can sound like and will definitely be considering them going forward in my hi-fi journey.
Okay, phew, back to other speakers then. @medium_grade, have you heard the Omegas? The Super Alnico XRS (with a pair of matching subs) was a possibility that I identified early on but was worried about (1) the lack of a crossover and (2) whether the 6.5" drivers would be able to output the clean, deep bass that I would prefer for my electronic music. I'm not sure why the lack of a crossover concerns me, maybe it shouldn't, I've just never heard of a speaker without one before. I also know I was just terribly spoiled by listening to the 15" woofer on the Volti Luceras so how unreasonable is it for me to expect similar bass performance from a smaller speaker?
To all others: I am definitely still Devore, ProAc, and Audio Note curious.
