Can not say anything about
YG speakers, I've never auditioned them. I've got Dynaudio Audience 72 quiet inefficient speakers (86 dB)
Currently I have PrimaLuna Dialogue Seven mono blocks and run them not even in ultralinear (70 watt) but in triode mode (40 watts).
I'm very rarely put more then 50% of power output, like ~ 75% because it's waaay too loud.
BTW this PrimaLunas amps to my ears best sounding amps (for any price) I've ever auditioned in my 30+ years of audio hobby...
