I have an un-switched double socket.
I've read that the left hand, earthed socket is the best of the two to use.
I'm curious as to why that is ? also one side takes my 4 way power bar mains extension which holds my tt power supply and and cdp.
Which way round / side would you recommend for amp and then the extension block holding the tt-ps and cdp

April 1st not for another 4 months, Robbie.
I imagine it will depend on the manufacture. I suposse, in theory, the one that has the screw connections closest to the pin contacts.

I doubt it really matters. Here is a diagram and yes earth is closest to the left. Give it a try and report back if you hear a difference. |

I found the socket with the earth connected direct was always a better sound.
Usually the left, occasionally it is the right.
Testing it out made me smile as it seemed crazy, like so much of what we have learned
ONLY ! if you are competent and confident you can TURN THE POWER OFF and check for yourself
If you have any doubt get in a professional

I find that grounding boxes minimise the effects of mains earth, although do remember that mains earth's primary goal is safety in the case of a defect.

Right! Been listening through an album this morning. In truth, moving the amp plug from where it was on right side to left side resulted in a slightly muted, slightly subdued/less open and dynamic presentation to my ear. I tried to be subjective by pretending I wasn't hearing it or being influenced by what I was hearing towards making me appreciate something about it, ie: identify any benefit/improvement. After two sides, I swapped things back/around, so amp plug in right socket and tt-ps into left socket. Whilst subtle, there was definitely more energy, openness and enjoyable boogie/groove to the presentation. The slight subdued/'laidbackness' I detected with amp in left had gone. Maybe my earthing is on the right side socket - no idea. Either way, I'm leaving as was as sounds better and more enjoyable / musical to my ears. Why this is, well as my dear older friend often replies whenever I've asked him the reason for something we've been discussing and he doesn't have the answer - "F&ck3d if I know Robbie"....  |

It might be due to the connections at the back of the socket or it could be one side has more oxidised contacts than the other due to fewer insertions and extractions.

Good point Clive
One leveller
Assuming you have a unswitched socket - which you must of course ! -
Turn off that circuit
Plug and unplug a few times on each socket or use Deoxit or similar Mad Scientist items
Turn power back on
Compare

Yep - Mad Scientist Graphene for me but Deoxit is also good.
Repeat cleaning all contacts once a year.
