Actuality it looks better than you would think, notice how the THD rises gradually with output , this is how distortion is presented to us in nature, its natural for us to hear as such, this kind of distortion curve will give an amplifier a natural sound within limits.

JA used to do ms power burst to measure an amplifiers ability to output dynamic power into varying loads, it would be nice to see one done on this SET.
BTW and FYI, Steve over on Wallet Big Forum (WBF), uses one to power his Wilsons, no one hearing his setup has complained about lack of bass or dynamics..

"Within limit" indeed...how's that frequency response vs load? Audible 2nd?nt - kuribo 15:50:15 11/12/15 (6)

try it! you know you want to!

  looks reasonable at 2.83v , you see sumting .. ? I'm more concerned with the 10K SqW , maybe not something for ESL's :)

  - Look at how it varies with load, to quote the author: - kuribo 16:18:18 11/12/15 (4)
    "shows that the THD doesn't change significantly with increasing frequency, though it does increase alarmingly as the load impedance halves."
    
    Flat, load independent frequency response is important....

      Because of output tap, just keep the output tap lower than lowest Zmin and you are good and since its at the very extremes, it may not be audible when listening, especially if you are using limited bandwidth speakers or those overstuffed pint sized subs going to 20 hz .
      You know, the ones walking across the room when reproducing a pipe organ..

      - Better hope your load doesn't vary much no matter what tap you use....nt - kuribo 16:39:21 11/12/15 (2)

        BTW, all amps have increase distortion with lower Z loads, whats important is the balance and PSU size, even Bruno have to give into that one ...
