High value, high efficiency speakers for SET amps


Hi, Gang,
I know that some of what I want to discuss here has been dealt with in other threads, some of them quite old, but I wanted to see if any of you fine, knowledgable folks are willing to help update and consolidate some of this info in a more current thread.
I am currently running my new Audio Note Kit 1 300B SET amp with a pair of Reference 3A De Capo speakers. I think it's a fine pairing and I am really enjoying what the 300B SET experience brings to the table in terms of musicality and emotional connection.
Still the De Capo, while supposedly an easy load due to its crossover-less design (only 1 cap on the tweeter with the mid-woofer directly coupled to the amp), is "only" rated at 92 db efficient, and based on the most recent Canadian NRC specs, that rating may be optimistic.
So, I am toying with the idea of trying a pair of more efficient, deliberately SET-friendly speakers in my rig, something that might also play lower and with greater dynamic swing than the De Capo's. Note that the De Capo's have served me well and I am very fond of them, but I can't help but wonder if my lovely Kit 1 would shine even better coupled to a VERY easy to drive speaker.
Devore and Audio Note are obvious options - the O/96 looks really tasty. Unfortunately, both of those choices are out of my budget, which I'm thinking maxes out (for real) at around $1500. I am willing to consider used equipment.
Tekton Lore 2.0: This is the speaker that Eric Alexander of Tekton has recommended when we've spoken on the phone, based upon my medium-small listening room and amp. I've read the epic "Lore vs. Zu" thread elsewhere in this forum, and clearly Tekton has its enthusiastic fans here. What I wonder is whether the Lore 2.0 has the refinement of the De Capo in terms of resolution, sweet high end and imaging. Audiogon'er Mikirob has pointed me to the many rave reviews of Tekton's speakers and I'm definitely interested.
I've corresponded with the Sonist folks (who are super nice) but their really high-efficiency, nearly-full-range floor stander is out of my budget.
Then there's the "vintage" route, going after some used JBL's or other high-efficiency "classics" from the 80's (or '70's). I am not inclined to go in this direction, but mention it because it's been suggested to me.
And then there's Omega. I spoke to Louis some time ago and he recommended his 7XRS hemp cone model. But I know all the raps on single driver designs and I'm cautious, although I would like to hear from any of you who own or have owned Omega's.
I'm in no rush to make a switch but I am very interested in your thoughts. Thanks, folks!

JWM,
Not so much hot as "steamy." Been getting a lot of rain here and it's been really humid. Good for us because we've been in a drought, but the mosquito situation this summer is going to be intense, I think. :-/
A must hear would be the Teresonic Ingenium :

(be sure to watch in 720p for better sound quality)
Can any of you folks attest to the sonic differences between the various Tekton Lore flavors:
Lore Reference
Lore 2.0
Lore
M-Lore
S-Lore
I had the opportunity to borrow a pair of the Lore Reference for about a week and run it in my own system, so now I have a pretty good idea how it sounds. What I'm trying to figure out is how all the different iterations of the Lore differ from one another, hence my question here. I've corresponded with Eric about this a few times but would still love the opinions of users who've heard some of these different speakers side by side.
Hi Rebbi,
How were the Lores in comparison to the DeCapo with your SET? Did the higher efficiency of the Lore matter?

Charles,
Well, after three years of ownership, my De Capo's are now up for sale on Audiogon (and elsewhere)!
The Lore Reference is a VERY different speaker than the De Capo. It's not that the De Capo doesn't sound fabulous with the Kit 1 - it does, especially since I added the vintage 6SN7 and a Signal Cable power cord (thanks to Roxy and Almarg for those tips!)
The De Capo's are so much about finesse - astonishing imaging, coherence, resolution, etc. The Lore Reference is more about dynamics and expansiveness. With the Lore Reference, the Kit 1 sounds more relaxed and it plays far "bigger" than 8 watts! Really, I have discovered that a higher efficiency speaker makes the Kit 1 sound like a monster!
:-D
And of course, the Lore Reference digs deeper than the De Capo (although for its size, the De Capo is no slouch in that department, either), making music sound more fleshed out. I must say that I was surprised and impressed at how well controlled the bass on the Lore Ref was. Interestingly, it uses a smaller, Eminence designed, 8-inch main driver, as opposed to the big, bass guitar driver on the standard Lore and Lore 2.0.
Both speakers throw a large soundstage, but of a different quality. The Lore Reference is more room filling, the De Capo more holographic. I will say that I found the Lore Ref's imaging a little vague compared to the De Capo, but that may be a placement fine tuning thing, too.
So while I'm not 100% sure that I'm going with Tekton, I am convinced that there are benefits to moving on to a substantially more efficient and easy to drive speaker. I am considering a number of options, depending upon what I get for the sale of the De Capo's.
Interestingly, the fellow who lent me the Lore Ref's felt that, in contrast to Eric at Tekton, the Lore or Lore 2.0 would be too large for my room. Hmm...
I'll keep y'all posted!
By the way, if any of you have heard the various flavors of the Lore side by side and can comment on similarities and differences, I'd love to hear them, because Tekton's web site isn't much help in this regard. At last count, you have a choice of:
Lore
Lore 2.0
M-Lore
S-Lore
Lore Reference
