Yep, have a 5150 in my home theater rig - for now, just driving 3 Definitive Tech Mythos speaks - for me, a perfect marriage of tubes and solid state...more akin to a push-pull sound than my preferred SETs, but in the context of the video system it's just the ticket. Plenty of clean power, timbrally accurate, runs COOL and has that bitchin' blue glow thang happening.
