When the impedance of the OPT increases, the tube sees an easier load making tube amplification distortion lower. But this is in the expense of power, which may not be a big issue.This is only true for the case of triodes. Pentodes and UL are a bit more complicated than that. I would STRONGLY recommend that you get a copy of "Understanding Hifi Circuits" by Crowhurst. He does a step by step comparison of the operating modes using one tube type as a constant (5881) and how load impedance affects each mode as regards power, distortion, and drive.
