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!

Map's advise and ideas sound very interesting and could be a creative way to place the E's. Very tempting to try in my room.
Jet if you try it I'd like to know the results. Thanks.

Nothing else I tried in that room worked anywhere near up to par. My smallest least extended speakers ended up sounding spot on and trumping anything else I ever tried in there.
If you've ever seen a pair of floor standing Klipsch Heresys the setup is similar. Except Isoacoustic stands provide the isolation from the floor needed to keep bass clean and are adjustable to two different heights and various degrees of tilt.
Smctigel,
My office is 16x14x9, but rises to a peak of 12 feet for about 4 feet. Not to long ago I owned the Almarro model you use. Nice. It played well in this room with the Tekton M-Lore. I was fortunate to have a number of excellent EL84s, 7189s. I liked the NOS Amperex EL84s best. I paired them mostly with NOS Sylvania 3 Mica Black Plate 5751. Best, Rob
Jeff Day 6 Moons Review plus good word on the street prompted me to purchase them. Day used them mostly with Omega 3s. Day also had a nice EL84 shootout, you might consider going back and reading his results in 6Moon Archive. Rob
