Does anyone have any experience of hybrid valve and solid state power amps?


Hi guys

I ask this question because I recently had a listen to a JE Audio Dyad S400 power amp. I was very impressed by its performance, but, correct me if I'm wrong there don't seem to be many hybrids around, or are there?


What are your thoughts on how they compare to other designs?

Perhaps a well-kept secret but at $8,000 it's certainly not considered inexpensive. And there are a ton of other options out there at that price point. 
Vincent makes various hybrid amps and I assume they all work, and I've listened extensively to my friend's SV236 integrated and it's very clean and musical.
Van Alstine (AVA) has three hybrid amps in their line up.  The Fet Valve 600 R (300 wpc), 400 R (200 wpc), and the DVA 850 monoblocs (850 wpc).  I have no personal experience but have read multiple rave reviews.

Based on all these responses there are more hybrids offered than might be imagined.
