I use a radial for each piece of equipment and the results have been great. The circuits are the same length and star earthed. Seems you are already starting to realise the benefit of this with plugging the 500 into your radial and hearing a positive difference.

Important with one Spur onlyâŚ

This has been found by others (including us at Naim) to be a very poor idea - the whole system should be run from one spur.
The only exception to this is (maybe) plugging a lingo into an another spur due to its effect on the rest of the system.

Weâve tried 6mm and 10mm, 10mm was better. Weâve tried one circuit into a power strip, 3 circuits into double sockets and 6 circuits into single sockets.
The latter sounded by far the best to our ears. We do however use star earthing as I mentioned above.

Hi Mrhappy I notice you mention star earth with regards to your circuit could you elaborate on the wiring layout.

Silverback, the sockets are side by side and the 10mm t+e feeding each one is of equal length. The earth conductor in the 10mm t+e is 4mm, so I have added an equal length of 4mm earth cable from each socket to a single 10mm earth cable that runs back to the same consumer unit bussbar as the sockets.

Okay thatâs clear, I have 3 unswitched sockets fed with 3 equal lengths of 10mm t+e running off a new totally separate consumer unit.
Not sure I totally understand why you have added the extra Earth cable , have I missed something here, just curious.

Not at all, what youâve done is correct, but I wanted to add the star earthing that I kept hearing mentioned.

Thanks for the reply, understand a little more now.
My electrician who is a good friend couldnât be stop laughing when I asked for his help, â you lot are crackers!â accompanied my more laughter but it was something I always wanted to install, so we got there in the end, every little bit helps.

Just out of curiosity, could you shut down two of the unswitched sockets at the trip to isolate them and run one unstitched socket with say a six socket trailing lead and the amp from the two plug sockets? It would be a bit of a ball-ache but might sound better? Not many of us have three runs, so could answer some questions for those that are curious?

I have been separating cables and generally doing small things to see how this affects my system. The 500PS and Supercap 2 sound great on Radial. Then block from Radial, 555PS, ND5XS2 and Phono stage.
System is sounding awesome. Moved speaker cables away from powerlines and internet cables. Keeping cables as separate as possible. All burndys off the floor.
Itâs there!

Hi Geko, worth a try, I do actually have a custom made mains block (friendly electrian again) that I used before the dedicated sockets where installed could definitely give that a try, in all honesty never thought of that as an option , cheers.
Apologies for any bad grammar or misspelling, very large fingers on very small keys 
This is a pre 500 series verdict.
Having preamp and power amp plugged direct into radial sounds more direct to me.
I have kept Lingo 1 off radial and run it on ring main with everything else, it has mains inlet upgrade by Class A. But like to keep it separate anyhow.
Itâs experimentation and how good it can sound. Powering up friday night now. Listening to loud house music. Loving this vibrant, dynamic set up.
The 52 500DR NDS set up absolutely blows the house down!

Hi Dan, I think the higher up the chain you go especially with a large number of components of the quality of yours and others on the forum it makes total sense to try and keep everything in check, as they say âthe devil is in the detailâ and from what I have read and experienced a little bit of attention to detail makes total sense.
Glad to hear your enjoying the 500, I canât fault you with your replaying levels, a man after my own heartđ

The NDS sounds absolutely amazing into the 52 500DR combo especially with cable dressing and changing sockets into mains. Powerlines on everything.
I think a better block for 555PS, ND5XS2 and phonostage may help further. But tbh, will leave it for now.
It sounds so damned good.
Swapped over to LP12 playing Muse. Sounds gorgeous. Wow! What a lucky boy I am to have this system!
Bl##dy well deserve it too!
Thanks to everyone who has backed me up on this one! I appreciate it. It was a big, bold move!

The comment about Lingo was about Lingo without the mains filter removed.
When I had 552/500 I preferred one spur and star earth .
Great keep on dancing

The 500DR has now been installed for 11 days. I am listening to more music than ever before. I am now listening to alot more vinyl.
I have done a number of tweaks with cable dressing and used trunking for ethernet cables and AV speaker cables. I have tidied up the Naca 5 and dressed it as it should be. I have separated the powerlines so they donât touch speaker cables. Supercap 2 and 500DR and mains block all direct into radial.
It sounds really sweet. I think everything is now settled down but I could be wrong.
The added weight of the 500DR on the middle stack has meant that records arenât jumping around. I am having no problems being sure footed around it. So I will leave the subfloor as it is for the time being.
With battling cancer I am trying to make things as best I can but donât want to do unnecessary work right now.
So what next? Sit back and enjoy the music. Of course I am pondering upgrades, who wouldnât with starting a 500DR. But sources and preamp are all sounding very resolved.
I think best course of action is to listen to the music and see if the 500DR changes with the weeks. Some say it will, some say it wonât!

You will certainly change the amp wonât.
Itâs built with partâs that are designed to do whatever they need to do, if these now change then they are simply poor itemâs.
You can have a bit off burn in on a new product, you can have a day or two to warm up, but an amp will certainly do both them itemâs much faster than anything else in the chain.
But you as a human will change each day thatâs normal.
I would do exactly what i am doing, sit back and just relax, enjoy, and try finding nice vinyl. Much more rewarding and fun
