    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.

    Apologies in return.

    From my perspective, and we know it is personal experiences which count here rather than rights and wrongs, I feel compelled to "go on a bit" (what I would call be persistent) if I ask a relatively straightforward question and the answer is ambiguous, incomplete, sidesteps the central point or whatever. I hate circular arguments so I try to turn them into spirals where they home in on an answer. We have been around this buoy so many times and I STILL don't understand your mains topology. and the only reason I'm asking is so others can understand what they might or might not expect to hear if they invest in something.

    I'm not at the other end of the subjectivist-measurist spectrum from you; I hope for example to take up the offer shortly of a visit to a cable manufacturer near here to hear the differences between various cable in their range and will not be taking any scientific instruments with me or expecting them all to sound the same... I have dedicated mains, a mains cleanser, isolation platforms, and (winces) probably thousands of pounds worth of speaker, interconnect and mains (but not digital!) cables in my relatively modest system.

    Somehow you and I got stuck somewhere early in this and have negotiated the buoy manfully since. If I've been painfully persistent, it's because the buoy has remained tantalisingly close but frustratingly out of reach. And no, I'm not a sailor: I know you're supposed to avoid a buoy not head for it, but where's the metaphor in that?

    Happy to let this thread wither on the vine; it's taken way too much of my day today and I need to put my energies elsewhere tomorrow.

    Sleep well.

    Well my house is still using a 60s system in which the -ve is connected directly to the earth at the CU by a thick metal bar, and it is still legal.

    I have a row of fuses, archaic looking with asbestos backings to the ceramic holders, and it all seems OK.

    I have been quoted about £600 to update to RCD form, but need to decide on this issue in discussion before considering future plans.

    If that was the result of what I wrote, then I assure you it wasn't intentional. I was in fact trying to be the opposite, as folks here who know me would appreciate. I'm honestly not the type to 'sidestep' anything!

    Well... Barry's a good friend of mine, and has visited my house and heard/seen my system and mains set-up numerous times, so you can take what he's written on that subject as a given, which you appeared to understand earlier, and therefore can now use to clarify matters.

    Glad to hear it! Cool

    As am I, and for similar reasons. The whole issue with the linear NAS PSU thing is not for anything to require proving, but simply to relate experiences that others can use to ascertain whether they wish to try the same thing for themselves or not.

    At the end of the day, we can debate the subject until the cows come home, and also the efficacy of what I've done in that respect, for the perusal of others, but the ONLY way you'll ever know for sure if something works or not is to 'suck it and see'!

    Hope that helps, Russell

    Thanks! That does describe what I see. Yes here in the states we have breaker boxes, new versions of old fuse panels but with breakers in them, and grounded 2" x 4" boxes recessed in the wall, with receptacles flush, sometime they are surface mounted on brick walls etc. I've always assumed everyone else did too! So thanks for the look, I'm enlightened.
