Once you try an OTL amp there's no going back, tubes actually connected directly to the speakers. The cleanest sound I've ever heard! One thing to be aware of with an OTL amp you MUST be aware of the impedance of the speakers and match them accordingly. This is more important than other amp/speaker matching IMO.... not to say this doesn't make a difference with other amps and matching to the correct impedance, it's just more critical with an OTL design.
