Romy,Choose an LP with considerable low bass information, and record it to digital the best way you know how, but with the Melqs not even turned on (or running at very low SPL.) Then compare play of the LP at high SPL with the digital playback at the same volume. The LP will now get feedback effects to the TT but the digital will be largely immune. The delta between them will be a measure of the TT microphonics (I assume the delta due to your best digital record/playback cycle is negligible, I think you said so.)Cheers,JJRerurn to Romy the Cat's Site
