Apologies, I'm not taking things personally, but you do go on a bit, essentially stating the same things again and again that we simply disagree on, which only serve to prolong an existing circular argument.

We're not big on circular arguments here or those who insist on always being right, especially when playing the 'science card'

I think it's best that we simply agree to disagree on what constitutes as a 'dedicated mains set up' for a hi-fi system, and where the likelihood of the sonic improvements brought about by the introduction of the linear PSU for my NAS drives originates from.

Marco.
