I have Transcendent OTL & 811 SET. The SET sounds like a toy compared to OTL. If you like tube sound then consider Transcendent. Atma-Sphere is another fine amp but haven't heard it so can't comment.
Sound of OTL Amps
Trying to get the collective wisdom out there on OTL's. Does OTL's approach the "live sound" better than SET's or the bridged design of the BAT's power amps ? I guess it depends on what aspect of the illusion of live one is looking for. But let's say it was clarity and transparency, which technology is best. Suppose it was the magical midrange - does this mean SETs is automatic winner. For those who own OTL's, why do you prefer these to, say, a 15 Watt SET.
