Surely you're taking the piss !

Great to see you in print and hope you are well. Reports (on this thread) of your demise were obviously greatly exaggerated, as I posted at the time.
Mike, have you told your home insurance company about these changes and has a part-P qualified electrician been to sign off the mods???
Gosh, there's always one...........
Hello Davech,
Just finished reading your magnificent tome, which I found extremely interesting.
Id also be interested to read your account of how the musical presentation, dynamics, soundstage, flow, imaging of players and instruments, changed/altered with regard to the number of modifications/upgrades you made. What music/artists/ albums did you play and what impact did the new changes make to those specific albums and tracks? Does the music communicate better and is it more involving? Do you end up going to bed in the early hours because the last track you were going to listen too became the whole album ?
Davech, I believe it may be prudent/useful for you to start a new thread of your own using the original posting you made here, which I believe is now somewhat lost on page 17. I suggest this course of action because it appears from the recent replies that the contributors here are more interested in electrical minutiae, than the quality of the music.
Praise to your Electrician.
I would comment that your electrician is to be congratulated for installing the 80Amp rated 16mm2 T&E, a hand-numbing task! To my knowledge you are the first in the world to have gone this 16mm2 route. Anyway I may be able to put more of these Hi-Fi installations his way, if he is interested, as people often ask me for a qualified electrician to do this work.. Bizarrely, Ive had recent reports of electricians who scorned & denigrated their customer and refused to install anything larger than the 32Amp rated 4mm2 T&E indicating that the whole installation is a complete waste of time and money. They are of course correct in believing the THEORY that compels them to form this view. If we were to use their THEORY and perceived logic then a single run of 1mm2 T&E lighting cable rated at 14Amps will be more than is necessary to power all the Hi-Fi? After all if one just adds up all the current rating of the Hi-Fi equipments internal case-fuses then this total will usually be below 14Amps and the circuits in question usually draw no more than about half that current approx - 7Amps?
From my experience & perspective a system so powered by this 1mm2 T&E would be unlistenable and normally Id score below 3/10. Assuming a Hi-Fi system costing £10K that would equate to £7K of wasted potential.
Best regards

A hard wired Beast is a power chord that Roy makes himself and it is hard wired (no plug) straight into a dedicated consumer unit
Because I found it by chance today trying to find suggestions on how to wire up for some new Meridian kit! So while I'm here, is the consensus that a radial approach with a dedicated wire for each outlet is better than a separate ring-main as recommeded elsewhere?
Not sure that you'll get a "consensus" because some of the Pommies who frequent PFF are wrapt in their antiquated 'ring' setups. But I think you'll find every other country in the world uses 'radial' circuits.
A dedicated wire from an MCP in the Consumer Unit to each wall-socket certainly is the ultimate, AIUI. However, IMO you can gain nearly all the advantages of this, from having 3 or 4 circuits - in my case:
* 1 for analogue sources (eg. preamp, phono stage)
* 1 for digital sources (CDP and TT PS
* 1 for power amp (or in my case, 1 for each channel).
And Roy's recommendation is to have all the wires the same length - so there are no earth potential differences at the wall-sockets.
What is important is to use the thickest mains wire you can get hold of (to give you minimum voltage drop along the wire). In Oz, for domestic situations, that is 32a mains wiring - which I think has an area of 6 sq mm.

Andy
Could be to do with our earthing too... isn't radial a ring?
"Radial" means a wire from the MCB in the Consumer Unit to a string of wall-sockets. It ends at the final wall-socket.
A "ring", AIUI, ends where it started - at the MCB.

Andy
Ah ok.. well we used to have radial tyres and as tyres are round I thought they were the same thing
In the UK we call a 'radial' that a "spur" which is what I have from the point of entry into the house > henley block > LARGE spur to rear of hifi > CU > dedicated 'spurs' into each piece of kit via a RCBO (if I remember correctly)... the bedroom system has the old electric shower 'spur' extended into the bedroom via a 15 amp socket into a star spurred extention cable thingy...
Both sound good.
Hello
New to the site do you have Roy's email address so I can ask him about the mains supply installation.
Kind regards
