I read the thread "Suggestions & ideas for 2.1 w/80s ...", which talked about tube amp a lot. It makes me want to get one. At the price range about $1k, I found a lot positive review about PrimaLuna ProLogue one, but how about Onix SP3. It's hard to find online reviews about it. Personally, I think it has better looking than PrimaLuna.
Any information and recommandation about tube amp are appreciated.

My currenct system is:
Speaker: M60
Player: HK DVD/CD player
Receiver: HK AVR225
Currently, I listen to two-channel music through my surround system.
Thanks a lot!
