I have owned an SET and have had a lot of time listening to OTLs. The SET has a glorius midrange, with an all most technicolred glow to the music. I don't mean this as a put down it is quite beautiful to listen to. The sound of an OTL is much less colored and much more dependant on the source and the speakers. It will not make a poor source or poor speakers sound better. It will how ever let you hear the fundimentals of music like nothing else if you have a good soource and good speakers.
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?
