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!

My best advice is to always make sure the technical indicators (specs measurements and any other factual technical inforamtion taht might be had via reviews, articles, etc.) line up first. Those are the best FACTS one has to work with towards the goal of OPTIMAL PERFORMANCE.

Optimal Performance is always a good thing but alone not assurance of what will be perceived as good sound. For example an all tube system and an all SS system might both be top notch performers together on paper and as measured, but each will still have their own personal preference for whatever reason. PErsonal preferences are subjective judgements that has no assurance of translating to another whereas techical facts to the extent discernable to help assure optimal performance does.

Check out common sense audio. they offer their own line of full range drivers (audio nirvana) with many options along with lowther drivers. I listen to a pair of 12in full range drivers(audio nirvana) with a 3.5 wpc amp and they are gorgeous. They have a guy who builds cabinets as well. just a thought if you want to go that route. most designs are 96db rated.

Veroman,
Thank you.
I have been on the Audio Nirvana web site and I had a couple of phone conversations with David Dicks, the owner, back when I was considering how to get into SET amps. He has a house-designed, Chinese made 300B amp that goes for something like $1550, delivered (which I'm dying for somebody on Audiogon to buy just so I can find out what it's like at that price)!
Now that I've built a couple of electronics kits, the thought of trying a DIY speaker has definitely occurred to me. In fact, if the ANK Audio Note speaker kits weren't so darn pricey, I'd try one of those.
If I came into a little spare cash, I might very well build a speaker from the Commonsense web site, since the total cost is very reasonable. Exactly which drivers are you using? And did you have someone build the cabs or did you do that yourself? I don't have any woodworking expertise, nor any of the required tools (saws, clamps and so on) so I'd have to factor that in to the cost, as well.

Rebbi,
I'll sit here and laugh my evil laugh joyously listening to my various Tekton speakers (M-Lore/Lore $650 and $1,000 respectively).

I did refer you to that Tim Smith Wall of Sound review previously, more than once in your previous threads. I also alerted you to a number of other Tekton reviews from the likes of Enjoy the Music, Part-Time Audiophile, Positive-Feedback as well as some others. Every review comes to the same conclusion: Tekton speakers are excellent top to bottom and checks all the audiophile boxes.

For $1,500 bucks you cannot do better. My De Capo vs Tekton-Lore shoot-out was no contest in the bass, Tekton clear winner! On every other parameter the Tekton was as good or better. Tim Smith liked the M-Lore better than his Harbeth 7s amongst others. The Lore is even better.

If you got $2,100 for the De Capo I'd get the Lore 2.0 for $900 (8 ohm, 98db, 30hz) with the money left over get a good power cord and interconnects. It will kill the De Capo.

Last comment: you could also have Eric Alexander put in a Mundorf silver cap, it's inexpensive, raises the bar even more.
