Erm... the CPC supply is like £18... I don't see how powerline filtering will remove the airborne RFI generated by the stock PSU - in fact it doesn't. Any AM radio makes a great test tool for this. Just stick it near the supply! It might stop noise being injected back into the supply lines though. I agree, this is all about noise and nothing to do with "juice" (the regs inside the SB will make sure of that).
