It's mainly surface noise floor when I am running a record. My TT currently sits on a cheap 15$ Ikea table. The floor also has a heater unit, which is usually more active during the night. TBH not really sure if the noise floor is an electrical issue or comes from various vibrations.
Proper isolation for a turntable really needs a proper isolation table. probably not cheap, but when I last met one, it hadn't cost its owner anything like what I expected.
I don't know how we we managed when we used to dance like a herd of rhino to the turntable. Well, ok, I do: its shelf was screwed to the *wall* and was thus isolated from the the wooden floor.
I think i need to understand this earthing part is bit more. In terms of noise I have 2 problems
1. Radio signal pollution
2. Surface noise when I play a record. I low hum, that bothers me a lot on the quiet tracks.
@Thad E Ginathom How can we make sure that everything is properly earthed? For now I have connected my TT, phono and amp to all different wall outlets directly.
This is what I mean when I say that listening to music just should not be that much hard work. If it is, you are using oversensitive kit, there is a setup problem or... as @famish99 says, maybe you should be listening to digital
... I'm not the one for detailed TT advice: mine has been in the cupboard for a decade. But before that were decades of childhood shellac followed by vinyl. The only major problem I ever had was hum, which I fixed by earthing the TT/Amp to house metal pipework. Just connecting those earth tags together was not enough
... There's something called an earth loop. Can't explain, but I expect google can, but I do know that it is notorious for causing audio hum. Check that out.
Also, try connecting all that kit to one socket. They may be on the same circuit anyway --- or you may be introducing some voltage difference earth to earth that could be a problem.
If things change when you touch stuff, I think that really points to earthing. But I'm no electrician.
Old houses in England used to have pipes for gas fires in every room. Maybe you have central heating radiator pipes? All conductive pipes should be earth-bonded. Try taking a wire to something like that if you can. It solved a problem for me once.
Stupid question... I suppose at least one of those devices you have linked the earth tags on /has/ a three-pin connection? Used to be a given... but my current integrated amp, which is not that young, has only two pins.
