Man....I am still undecided. I currently have a HiFonics VII 4-channel Jupiter pushing 4 Focal tweets, a HiFonics VII 4-channel Gemini pushing 4 Focal 6.5" midbass and a HiFonics Son of Colossus Gen X pushing two 15" Kicker L7 subs. I have a friend who just offered me $1k for all 3 amps. This past July Mr. Mantz gave my Gen X amp a good tune up AND signed the bottom of the amp for me. I picked up the amp personally. I'm now thinking of selling all 3 amps and going with 2 Kronos and 1 Leviathan. What do you guys think?
