What's best in highly sensitive/efficient speakers.

Isn't the nominal impedance of these speakers 4 Ohms? That's not exactly going to mate well low power-out amplifiers. In the Wilson systems I've seen, 300W-1000W solid state amplifiers seem pretty common.
believe the triple whizzer is supposed to take care of that. i haven't heard one though
Factor in multiple drivers, crossover... and you need current to make them come alive.. regardless of their specs.
I think the original X1 was a true 95db with an easy nearly 8 ohm load...it worked very well with a 30 watt SET.
That is a descent amount of power for those specs. My system is similar spec/ power wise and works very well. When I tried a 6 watt SE amp with my 95db spkrs, it was lifeless.
Yeah, 6 probably won’t work great if your room is big, you sit far away or listen loud but 30 will do nicely in most rooms.
It's been a while since you posted, obviously, but if you haven't read the Cube Audio thread on Agon, you should. User reports are near-universally positive. And I don't think I've ever read a negative comment about treble.

I know someone who has heard it says bass is not that deep and upper mids lower treble not refined. At this time not going any further with it.
What's you opinion on Volti Audio Rival and Coherent Audio loudspeakers, dear experts? With listed sensitivity around 100db they should be relatively easy to drive (not sure about their impedance curve).
Vitavox CN-191corner horn from about 1960, second iteration. They are 105 dB, 16 ohm loads and benefit from room gain with the low frequencies being loaded by a folded horn in back and using the walls, so very easy to drive with my 18w SET amps in a fairly small room.
I heard a cube audio nenuphar with SIT 2 and 3, this is the top model with their subs. Pass top model pre, and Rockna dac. Didn't like at all, the room was big and fine no issues there. Nothing wrong with the treble but nothing good about the speaker. There were others in the group who have heard that system with various amps and none like it. If I ever hear in a different set up will post

beautiful corner horn speakers. never seen or heard of them before But I like them.
Very very nice.Here's my WIP journey into the high sensitive horn world:

It is based on BMS 4592ND coaxial driver for 350Hz - 20Khz @118dB/W sensitivity. The base bin is Klipsch Belle without the top hat.
As long as your Reel ToReels outnumber your horns, you're still OK. At least that is what I am going to say when they come and fetch me.
Disclaimer: I'm a speaker manufacturer. Please take everything I say with a grain of salt.
Eyeballing John Atkinson's measurements, the impedance curve of the Volti Rival does not look particularly SET-friendly to me. The minimum is 3.3 ohms, and there is a more-than-20-ohm peak around 3kHz. Low end looks strong, and the enclosure is large enough to give good low end combined with high efficiency. The review is from 2017 so the measurements may be outdated.
The Coherent Audio speakers use what is arguably the best high-efficiency coaxial driver in the world. Those big Radians are what I would be using if I were doing coaxials. The ceramic version will have a bit more low end and might get away with not needing subs; the more efficient neo version would imo very likely need subs. I would expect the impedance curves to not dip as low as on the Volti Rival.
The one thing I cannot comment on is the most important - how do they sound? I have never heard a Coherent Audio speaker. I have been consistently VERY favorably impressed with the Volti Vittora, but have never heard the Rival. I have heard a Spatial Audio speaker which used the 15" neodymium Radian coaxial (with the aluminum diaphragm), augmented by a separate dedicated woofer, and imo it was in the same league as the Vittora.
The waters are now probably muddier than ever!

Is this your system? If so, tell us more!As long as your Reel ToReels outnumber your horns, you're still OK. At least that is what I am going to say when they come and fetch me.
