Holy jump!Nah. I went straight from a 25-year-old ADC XLM MkII to a Shelter 901. No baby steps, I'd never heard a MC before making that move. That was a Kierkegardian moment!
Davew, sorry for the hijack. I've never heard a Helikon so I could only repeat the experiences of others, which you can find with a little searching here or on VA.
