I can look them all up, but do you happen to have the power ratings into 4 ohms? Generally, you'll want at least a 100 watts into 4 ohms and more won't hurt, along with a relatively high damping factor. All VAs like SS power sections.
I listened to the Rogue Cronus with the Haydn's at a dealer. I am going to assume that it is not too far from the Prima Luna in terms of power and sonics. I was not too impressed. I guess I like the power/ punch of ss with the speakers. I was seriously thinking about tubes but I am not inclined to having the heat they produce as the amp is close to my bed; okay in the winter maybe but not in other seasons.
