I'm running mine off a Crown XLS 1502 525 watts into 4 ohms.
Surprise surprise they sound fantastic.
My Peachtree Nova 150 is serving now as a preamp. I just added a Schiit Modi 3 DAC (out curiousity for $99). Again, believe it or not this combination is sounding awesome with power to spare, big soundstage, dynamic sound.
One other comment I believe the Vidar's specification calls for 8 ohms (not 4) when used as mono blocks so you may want to check that.
Good luck on finding the right amp that works for you.
