Nice one Olster and very insightful. always the way with hif-fi, that there's something to sort, that takes a bit of time, time we often dont have, (been there, done that, got the t-shirt).
Indeed, do what you must and then at least you'll evaluate the Ti from a good platform, come the time.

Glad you got to the bottom of the parasitic noise Oli and good luck with the rebuild (I/we expect plenty of pics and words to follow the rebuild of both the plinth and the refurb of the PSU)  |

I was starting to wonder if i should just abandon the idea of high level vinyl! I will post refurb pics as and when i make some progress |

Sounds a great project to squeeze a little more out of an already amazing deck

I found that moving to the bigger room and moving/reconnecting the kit has made a massive difference to the SQ (and enjoyment) of vinyl listening.
Still much prefer it to CD or streaming (apart from the album I am listening to at the moment where the sibilance is very acute, no matter which TT I use so I know its not the setup but the LP.....)

I think my vinyl sounded amazing and still prefer it to digital as it was, so i am excited to see what happens when i sort these issues out. |

Has anyone heard this noise before?
The correct answer for the cause of it will win nothing, but will be correct.
Pssss...clue is in the title of the vid 😂

last time I heard something similar many years ago when I lived opposite a club and taxis were still on the old analogue radios
It was being picked up by the speaker cables.
Moved system to opposite wall (it was on the wall next to the road) and that sorted it.

Pssss...clue is in the title of the vid 😂 If you don't have a dedicated mains ring for your hifi (which I don't yet), I've found one of the next best solutions is to run all the horrible noisy appliances (router, NAS drives, fridge etc etc) off those cheap-ish Tacima power strips.  The filters in them not only seem to stop noise going into the equipment (which actually robs performance for audio components) but also stop noise from said components going back on to the mains. At least things seem a lot quieter when the main offenders are plugged into one of these. I also do the same with noisy stand-alone lights. As I say, maybe not the ultimate solution, but it may help if you are having noise issues. Routers in general are awful for this. |

Macca that is a very good idea and a relatively simple solution as well . I would agree with you 100% that routers can be very noisy little blighters and in very insidious ways you can find that noise getting through in digital reaplay over wired ethernet. Couple of very specific solutions that work is the obvious one if you have really strong Wireless use that it is easily powerful enough for music files , only issue is if you do not have a very good Wireless Network in which case this is useless. Second option is to place a network switch between your Music Server and Player and your router which will very easily get rid of any noise by breaking the ground plane between the two . Last option is over kill (guess which one I went for ) and this is to feed your router in to an Optical signal box then feed the optical signal in to your network switch which really does lower the noise to very decently low levels .

Its quite common, we have a very large internet pipe here for the business and its just not as good at streaming (if you have to) as a mobile 5G router which I have been using for four years now hassle free and 520Mps rock solid all of the time.
Welcome to the new world of high speed digital communications and it will only deliver more interference as the BW's go up, next your fridge will be dialing up 'Cold as ice' from Qoboz while it works out what to order from Ocado for the weekly shop, deep joy

Trouble is that this is airborne noise

Morning Oli
They are a couple of in line filters that can help give me a call and I can loan you one.
Personally I use a fairly non fancy 5G mobile router with an LPS not a subtle upturn in streaming SQ.

You can get Alan to knock you up a LPS for the router that will help, ferrites may do more than attenuate the noise on ethernet communications

I'm not saying it isn't, just that I'm not convinced. I don't use the internet for the system, other than for control of the streamer. Everything is native, and file based...no streaming. Yes, the router may be throwing Sh#t into the mains, so a filter of sorts may make a lot of sense, but again... behavior suggests airborne RFI. |

Oli
I only use the mobile router as control 75% of the time as streaming is abackwards SQ step for ourselves as you know.
But think about what you router is acutally connected to everything else in your home and ALL of the wifi how many pads/phones/games/tv's are connected to your hub?
With only one device dedicated for a single router the amount of traffic is very small
If the hub is close check to see if you are connected to your phone or controll via 2.4 or 5Ghz?
Next look at the channel hopping charactorists, different IP providers use different hopping methodology the closer those signals are togther the more bleed through and combined harmonics.
5Ghz is generally has less poetntial for IP drivered noise BUT it has limited range compared to 2.4Ghz
Easy way to prove your thoughts of radiated RF emmissions is using a near field closed loop RF probe even on basic SA or scope you will be able to view the FFT and easily identify the interference.
Personally I feel its cable borne divered so conducted emissions, however you can still see this with a slightly different near field probe as well.
Alan can knock up near field probe from some RG58 co-ax and use his SA easy to prove one way or another Oli.

have you tried switching off everything in the house except the stereo then switching back on one by one until the noise starts up?
It could be airborne but it could also be noise on the mains from another appliance. be sure before spending any money.

I left it till last. Defo the internet. I have a filter I can use to find out if it's the mains. But may need a lan filter to try that out. |

Switch off the WiFi on your router see if that changes anything

You have to log in to your router. Find its address and try logging in as admin. I have done it before but the details are hazy now  |

I just thought Oil
If you just use it for control just make you own internal network just a basic hub that doesn't need to be connected to any outside IUP at all cost abourt £30 that way just the remote control on the phone no hassle or interference at all.
