Goldenear Triton One.R - can it be driven with low power tube amp?

I’m happy that my initial query on this thread, and the stimulating ensuing discussion has occurred. The experiment with the Stingray driving the Tritons has given me insight into future mods that I may choose for this system.
For now the Stingray is not available, as it is the heart of another system - one that sounds even better, btw.  Were I to replace the ss amps in the Triton system, I would probably opt for SET tube amp(s) of at least 20 watts. Also, the Cary SLP-98P preamp is a temporary installation, and is soon to be replaced with my Cary SLP-05 that is currently being upgraded at the manufacturer. I don’t expect it to change the sound significantly though, as the 98P is excellent.
Life can be good.

"Life can be good" indeed.
I believe that you will experience further improvement with insertion of the Cary SLP-5. 

20 watt SET ?  Are you considering parallel 300b SET  or 845/211 tubes?

Both are future possibilities, but I may be perfectly happy with the Upgraded SLP-05 and Pass XA60.5s.
Cary is backlogged. So the upgrade could take a few weeks. 

Again George I don’t believe that anyone reading this thread will find it misleading or confusing. People can appreciate real listening encounters versus supposition.

Supposition? the proof has been given by two reviews and two bench tests with graphs.
These speakers load is way too hard for an 8w SET or low powered tube to drive from the bass 80hz up. who partners a 1200w lower bass amp with a 8w set bass/upper bass amp!!!

And Keith Howard would not have stated this if it wasn’t just a supposition!!

HiFi Review LAB Test: by KEITH HOWARD
We measured a minimum modulus of 2.9ohm and a minimum EPDR of 1.3ohm at 92Hz, with further dips to 1.6ohm at 219Hz and 2.0ohm at 584Hz.
So the One.R is a tough loudspeaker to drive, despite its powered bass section.

To anyone thinking of buying theses speakers do your homework when buying an amp, or you’ll be a fool soon parted of his money if you believe these speakers can be driven to their best by low powered tube "flee" amps.
Only this type of 25w "flee amp" will drive them, ones that can double their wattage all the way down to 2ohm. 25watt only into 8ohms, ML2 monoblocks from Mark Levinson

Stereophile’s Nov 2019 review of the Triton One.r has a few differences from the Keith Howard review.
Measurements indicate that the impedance between the critical 80 to 200 hz range is between 4.1 and 5 ohms. And at the 80 Hz crossover approximately half the power is being delivered by the internal amp.
Speaker sensitivity is 92 db. So about 1/2 watt at 80 Hz should get you to that loudness level.
Manufacturer recommends amps that have a range of 20 watts to 650 watts. 
From these measurements, the manufacturer recommendation, and my listening test, I have no qualms about using a high quality SET of at least that power level, that is spec’d for 4 ohm performance.
