I think you have already answered your own question: plug the power amp directly into one socket of the wall-mounted double, and the pre and TT into the other using a two-way adaptor. Using a multi-way block shouldn't make a difference, but clearly it does to your ears. Is it a 'cheapo' distribution block one might buy in Poundland, or an 'audiophile' item?
