The best tube poweramp. . What do you think about ?

I’ve now a VAC phi 300.1. I’m very satisfied with this poweramp. What do you think , and do you have another option ?
my set consists of: Audio Note Cd Two II , Metronome technologie C6 , Daniël Hertz M6L: and the Ilumnia Magister MKII speakers. ( look at : ilumnia.be ). Thanks a lot for the reactions!
