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?

Scott,
Thank you for providing the correct measurements.
I guess I would say that ultralinear sounds pretty forward / edgy with the Zu.
Probably has something to do with the bump at 2K-4K Hz that Kenny mentioned. With the Revel, ultralinear mode sounds more acceptable, but still a little forward / edgy maybe. Gonna take a look at some of the speakers suggested.
@stereo5, Had been thinking Triton 2+. Actually had those with this amp and it sounded pretty amazing. But I decided off axis with the ribbon tweeter was a problem, so I swapped for the Revel. Kinda wish I still had the Tritons.

If you haven't found a pair of speakers within the next 6 weeks, get back to me.  I am waiting for my GE Triton Reference speakers and will be selling my Triton Twos (not the +) at that time.  I am thinking around the 1500 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.
