Speaker match for PrimaLuna Dialogue Premium HP Integrated?

Hey Guys,
Wondering about speaker match for PrimaLuna Dialogue Premium HP Integrated.
Using KT150 and Mullard CV4003. So maybe 50 watts in triode and 100 watts in ultralinear.
Don't like ultralinear much. (GeorgeHiFi linked some curves showing ringing in ultralinear:
https://forum.audiogon.com/discussions/primaluna-dialogue-premium-hp-tube-rolling-suggestions-to-red...)
Setup is in a small room currently. Had used Revel F206 (which I still have) and now Zu Druid MK IV.
Revels sound pretty good but I don't think they show their best with limited tube power.
Plenty of power for the Druid, and it sounds pretty good but response curve seems uneven to me.
So Revel nice response curve but a little tame. Druid pretty lively/ fun but uneven tonal balance.
Anyone have a particular favorite speaker match up for that amp in the $3K-$5K range?

I misrepresented what George had said on a different thread.
I’m sorry I showed the bench tests/reports for the PrimaLuna DiaLogue Premium power amplifier. JA said:

"As AD found in his auditioning, the PrimaLuna DiaLogue Premium performs at its best with KT120 output tubes operated in Triode mode. However, that high output impedance, and the rise in distortion when the load impedance drops below the nominal output-transformer tap value, will make careful matching with the user’s loudspeakers mandatory to get the best sound from this well-made amplifier.—John Atkinson"

But looking at the graph the Dialogue Premium Integrated is also overshooting on square waves with any capacitance loading as well in Ultralinear, from the 8ohm taps not to mention distortion rises much so as well above 10khz.

any of the smaller tower (for your room size)and the stand mounted Proac speakers always sound wonderful with tubes. AudioNote speakers are very nice with tubes and designed for corner placement so giving you more room to play with.  just two off the top of my head.

Plugged the Revel 206 back in using 4 ohm tap and triode mode (based on those measurements, should be the best options), and now I wonder what I was thinking. Only someone with audiophilia nervosa (me?) wouldn't be pretty happy with what I am hearing now. Thanks everyone for all the comments.

4 ohm tap sounds better to me in my system as well.
I use triode mode for certain styles of music(acoustic guitar, vocal oriented) and UL for other (more complex).
Personally I don’t go by graphs, I go by what my ears tell me. For me the stock Chinese tubes in the center slots were my issue with my amp. (Dialogue Premium Integrated)
Most importantly I am glad your enjoying what you hear now.
