Tough one. I imagine few people have heard both. For what it's worth, I've had a number of SET amps (421A, 45, 300B, 2A3) in my system from time to time. No two SET amps sound the same anyway, but I'd say the LFD MKIV midrange and sense of clarity and presence is within the slimmest of margins of sounding like its in the SET family. It is also sweet, extended and beautiful. And of course it has better drive, better low end grunt, runs cool and I can just leave it on all the time.
