I own a 2550 50W Jubilee stack, and used to own a 2555 100W Jubilee head. I checked out the Helios pretty thoroughly at the LA Amp Show. Jubilees have a lot going for them, being higher gain JCM 800's.
The Helios is definitely thicker, like a highgain Plexi. It's a big badass tone, that's for sure.
But overall, I like the Ecstasy models more than anything else Bogner makes. They just cover so much ground from a Twin to a Hiwatt, to Plexi to a mighty roar. As a matter of fact, I really love the Bogner blue and red pedals as well. You can plug those into any edgy clean amp and essentially add a Bogner channel to your amp, plus boost.
I don't know how Reinhold did it, but he captured the amps in those 3 pedals.
