My integrated Decware dual-mono Mini Torii has the OA3 voltage regulator tubes (one per channel) designed so it would reduce noise by filtering it at the cathode jump of the signal through those regulator tubes (same principle). But, it is wired for 6V6's as a Pentode, and maybe for that reason it does not compete with my Inspire KT-88 Triode amp in SQ.
One thing I strongly believe in, as a somewhat experienced observer and user, is that the simple SET amp circuit is more direct and natural and less prone to unpleasant distortions relative to more complex designs. The only real trade-off seems to be heat dissipation and power inefficiency, secondary considerations when one primarily seeks SQ. Lower power levels are negotiable through the right speaker sensitivity choice and the listening room geometry and sizing. I'm sure someone more enlightened could correct me, for example, explaining why the so-called improved dynamic response in a Pentode arrangement beats the old man's Triode amp :), or how could a Pentode sound as good as a Triode, as in the proposed Universal design discussed earlier, assuming the same quality designer/considerations are applied in each case ...
