IOW, he heard differences in SQ among those listed load resistances BEFORE he decided to implement a SUT. So, using a step-up had nothing to do with his observation. So many hear differences using load resistances that differ by only a few tens of ohms that I am convinced the observations are valid. I just don't hear it, or better to say I do hear subtle differences between widely different loads (e.g., 100 ohms vs 47K ohms, with LOMCs that can drive 100 ohms) but none worth a damn. In those cases I slightly prefer 47K ohms. I do think my system is low enough in distortion that I should hear it if my brain says it's there. That suggests my ears and brain are tuned differently or are superannuated or both.
