I have a pair of Wright Mono 10's that are a push/pull 2A3 design. I also own a pair of 300B SET amps. The Mono 10's give that wonderful midrange magic of the SET while providing more authority in the low end and and overall dynamics and speed...this in direct comparison with both my 300B's as well as George Wrights wonderful 3.5 2A3 SET amps which I owned for a while. The only compromise, to my ears, is in the sense of airiness and delicacy that SET does oh so well. It is by no means a big compromise though. I've never heard the amp in question though, so cannot comment directly abotu that amp.
