Atma-sphere is certainly good, if is it the best, I don't know. In my case, OTL amps bettered heavy-duty solid state amplification. I had a flagship chain - Krell FPB600 driving Dynaudio Consequence speakers. I bought Atma-Sphere MA-1 and got them factory upgraded to mk 3.2, and to my ears, this sounds better. But it happened only when I changed from 8 ohm speakers, to 12 ohm (Audiokinesis). You get the diamond edge of OTL amps only through high-ohm speakers. If not, it may sound ok, but it is not optimal.
What is the best OTL out there?
Hello. I've always been curious about OTL amplifiers, but never tried one except for the very unusual (and wonderful) Berning Siegfried, which was both SET and OTL. I wonder if there is an agreement as to which OTL currently in production can be considered to be the best. Ciao.
