You’re missing the point. One of the purposes of a dedicated mains circuit for the HiFi is to isolate it from potential sources of electrical interference, and a router can certainly be that. Even switching power supplies on other HiFi equipment should be physically and electrically isolated from Naim boxes that use toroidal power supplies.
Very neat job. I currently have a 20 amp radial circuit off the main board with 4mm cable, 2 unswitched mk sockets. So yours is a stage further.
Have you considered a dedicated 10mm radial off the incoming mains as opposed to the existing consumer unit or are you happy with what you have.
I am hoping the new dedicated mains yields some further improvement. Guys on here say I should do it and it’s what Naim recommends, so I am prepared to give it a go.
I used the main CU and separated the earth, Main reason was to stop pops and clicks from fridge, thermostat and freezer, I now have none of that,
If that did not work I would have put in a separate CU.
Yeah, when I did my radial circuit sorted out problems with my AV gear from fridge. It is a very good solution. You have gone a step further than what I did initially.
Guys on hear and Naim say ultimate solution is dedicated mains.
Will wait until my electrician comes over to have a look which wiĺl be in next couple of weeks. I won’t push him as working outside isn’t great at the moment!
I understand this. However, if the router becomes a part of the hi-fi system, as it is when streaming either from internet services or local files, then I would say there is a counter-argument that because it now forms part of the system it should be on the same mains feed to ensure optimum musical coherence. This despite the down sides which I fully acknowledge. It’s a grey area and I don’t claim to be 100% sure here but I know that all components should share the same feed for optimum performance. I don’t have a dedicated mains but my system is fed from Chord M6 block. So that’s CD player, amp and Chord Qutest SMPS plugged into the block. Now clearly the Qutest PS is noisy so one could argue that it would be best plugged in elsewhere. I’ve tried that and it sounded worse.
None of this is definitively scientific of course. It’s all very much empirical ‘suck it and see’ type stuff. It is certainly worth experimenting rather than making decisions based on assumptions which may turn out to be incorrect. My experience over very many years of this hi-fi game is that often things don’t happen in the way that logic dictates that they should.
I agree with suck it and see (try it out yourself and make your own mind up)
However … whilst it is perfectly safe to have your router and streamer on the same circuit, it’s generally accepted that separating them is preferred to reduce electrical noise that degrades audio SQ.
The items of most concern are SMPS’s and the routers SMPS can add switching frequency noise back into the AC that can potentially cause streamer DAC jitter issues.
FWIW, I’ve installed numbers of ferrite chokes on all my SMPS ( the correct ferrite ‘mix’ on both AC & DC sides) and that for sure works for me.
Yes SMPS’s are very noisy and routers especially are. Incidentally our router and ONT box are both plugged into a Chord S6 mains block and we have two Chord Ground Arays plugged into the router (a legacy from when we used to stream - which we no longer do). The TV/Blu ray player is fed from a separate Chord S6 block and the main system (Moon 260D CD Transport/Moon 340ix amp/Chord Qutest DAC) is plugged into a Chord M6 block along with three Chord Power Arays. We did try a Chord Power Aray Professional which was really superb but at around £5K we couldn’t really sensibly afford it so had to pass.
Everything is on the same ring main which we have attempted to make as quiet as possible. One interesting thing. I tried unplugging the Chord S6 block which feeds the TV/Blu ray player thinking that it would improve the sound of the system since that’s two noisy SMPS’s removed from the ring. It sounded noticeably worse. I was puzzled at first until I realised that unplugging the S6 block was also removing the noise absorbing components in that block from the circuit. So it was obviously more beneficial to have it plugged in, despite the noisy TV/Blu ray player. Of course I could just keep unplugging the TV/Blu ray player from the block when not in use - but honestly it’s too much hassle.
