Good news is stereo equipment is not a zero sum game. Many of us have multiple amps and can enjoy the unique characteristics of each without needing to declare any particular amp "the winner". I happen to believe both SET and OTL's are wonderful topologies and think audiophiles need to experience listening to both. Long ago I fell hard for SET's and have acquired 45,2A3,300B,F2a & GM70's. While tonally the tubes are different from each other, they all share an amazing sense of presence. SET's simply put me into the music. More recently I have also acquired an Atma-sphere S30 and am continually amazed by this little OTL. While my SET's are colored to one degree or another, the S30 is crystal clear, has wonderful liquidity, yet also packs a bottom end punch that my SET's can't compete with.
Unless you need to rock out at high decibels, I would venture to guess that a SET or OTL would be a more satisfactory experience than a Spectron (which I've heard - it did nothing for me).
