ECC88 was not included in MJ's measurements. That may change for the 4th edition (whenever THAT comes out), and he's aware of several tubes which show even lower distortion than the 6SN7. Don't ask me what they are, I'm not tellin' until I have the market cornered.

But here in tubeland we also have this inherited belief that such distortion measurements have very little/little/not a lot (pick one) to do with the perceived "accurate" reproduction of music. Otherwise, wouldn't we all be listening to solid state devices that give vanishingly low harmonic distortion measurements?

  I'm not so sure, all things being equal, that SS devices are lower distortion. In their traditional use and circuits maybe but that's not comparable topologies to valve circuits AFAIK.

  A circuit which does not have good linearity will not be accurate. You might LIKE it, but it's a signal processor.
  
  This is VERY different than saying that low static distortion is sufficient. But it is necessary for accuracy.
