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!

Reno take a look at isoacoustics stands on Amazon if there are a size that would fit. Isolating stands and platforms like auralex subdude seem to take imaging soundstage and detail to a higher level in my upper level rooms not at foundation level.
I heard the Audion-Note AX-2 with 300b SET, it sounded awesome, had smooth treble, clear mid-range and bass good for the 6inch driver and SET had no problem to drive them effortlessly, however the sound stage didn't have the depth and width of PMC twenty series when compared side by side.
So are these the "ones"?

Nothing wrong with not being totally enamored with something and saying. I bet even Tom Brady can find something not to like about Giselle.
Regarding the Audio Note speakers, I just saw a pair on higherfi web site that shows a retail price of $250,000.

I didn't realize they could go that higher. Then again, the site is called "higherfi".

Next time I hear AN-E at a show and like them, I really need to nail down which ones they are exactly and how much they cost. They are usually among the best, but for those prices I suppose they should be.
I'll check out the Roku. Their box technology for music streaming was not up to snuff with Amazon Fire TV box when it first came out, but things change. I used a pair of Roku Soundbridge Streamers to external DAC several years back prior to Squeezebox. Those sounded very good, undistinguishable from Squeezebox Touch into same DACs I thought at the time. I still have a couple sitting around unused but the hardware and software is somewhat dated these days. But I have been hoping Roku would get serious about music streaming again ever since and figured maybe it was just a matter of time.
