Best SS amp for Zu Druid Mk IV speakers

AudioFeil, I realize you sell the Zu line. I was wondering what you consider the best SS (price no object) watts to drive the Defintions? thanks in advance.
Sorry, Saffy, for getting a bit off topic, but while I have Bill, I'd love to get my this question anwered.

I will second Bill's recommendations and add RWA 30.2 battery chip-amp to the mix. But First Watt might be the better choice - depending on your personal taste.
It is not the question of which is the best SS amp but what works with Zu speakers. There is no definite best but what works and what doesn't.

If tube amps are open for consideration, I would suggest Melody M2A3 monos or M300B monos (I own these and heard them with Zu Definition and Druid - perfect match IMO).

I have used several low power SS amps to drive my Druids, and the the First Watt F3 wins hands down. Other contenders where:
1. Various chip amps ala Patek
2. Class D (tripath)
