BTW, after I reformed the original Radiospares mains filter caps, and did it correctly this time, it does seem to sound a little better and with less ghosting. Still undecided if it sounds as good and has as little ghosting as it did with the Sozo Royals, but at least reforming was 100% successful. They passed ESR and capacitance tests with flying colours and the voltage drop came down to less than 0.5V, so they seem to be perfectly fine. That’s pretty amazing for 55 year old caps. Say what you will - those old caps seem to have been made very well.
