Hi guys, a tube amp for my micro utopia be

I just bought a gryphon atilla for my micro be, but find it was a failure, wanna change to tubes.
Here's my list:
Jadis DA88sorDA60 if possible
Cary 300 sei can be run as well as my headphones,but dont know it will match micro be or not.
Cary aes six pacs plus ae-3 mk2, (heard great comments about it)
Mc 2775 or
anything else can be recommended. I'll be very appreciate
