The Moab is not an easy load (per the Stereophile review) though is was measured as 93dB @ 2.83V.

Looking to move to a Tube Integrated setup
I'm moving from solid state class D to a Tube Integrated amplifier and have narrowed it down to (2). The Ayon Scorpio II w/KT150's and the PrimaLuna DiaLogue Premium HP w/KT120's. Does anyone have any experience with either or both of these they can share. Recommendations? Others I should consider in the $3K to $6K range? My speakers are relatively efficient at 98dB.
