TO be SET or to be OTL that is the ques.

Everthing i read or hear about the Joule Electra or the atma-sphere is great. Either the M-60 mark 2 or the vzn-80. I'm trying to decide to go with the SET or the OTL route,& can't make a decision.The large availbility of the SET's out there make it even more difficult. If someone could shed a little experience I would be most grateful.Probably if I go the set route I will consider the cary or maybe antique audio maybe bel canto, who knows?
