abraxalito,
Yes wheres that annoing sound coming from ? It seems to come from the surface of the drivers. I might have to go down and by some more expensive speakers. It totally ruins my listeningexperience.

That's a good way of putting it ... it's a fascinating behaviour, no matter how one chooses to interpret what's going on - you're staring at this dang driver, working its head off, and it might as well be a lump of wood ... 😀
I agree - noise coming from the surface of the drivers is annoying. It'll come from the electronics (DAC, preamp, amp) you have feeding the speakers. Don't waste money on better speakers - they'll only convey the noise to you with more fidelity.
So describe for us your upstream electronics?

abraxalito is right on the money ... it's all about the rest of the chain injecting distortion artifacts, which are extremely obvious when you're close to the drivers themselves. Diagnosing what the source is, is the battle many times - how easy to find a solution is a, depends...
Ooooh, that's so bloody annoying, when it happens !! I always do a select all, and copy, and possible paste, somewhere else, before sending a biggie - just in case!

about my stereo:
Clean homemade power to laptop with soundfiles and DDDac single deck, blueboard (wireless connection) into various amps (I like swapping them). Out to Snell J lookalikes.
Vinyl, of which i still listen to a lot, goes on an old, but goodie Dual with original arm and Ortofon 2m Blue into a Borbely phonoamp.
In my other home everything goes, as there is no backgroundnoise and no neighbours, to
consider. Thats where sound goes loud and everybody is happy. Thats with Troels Gravesen OBL11 (T25) speakers. They have enough space to breathe and fatigue is an obsolete word.

Do you have any classA amps amongst the ones you swap? I ask because classAB is a major source of that annoying noise due to dirty power supply rails within amps.
And
I have a vintage Sugden, a Radford STA15 and a newish Hiraga 2x8w.
NAD D3020 for convenience and a host of fiddleprojects, that sometimes work and mainly is in pieces. For partypower i use a "pro" A/B job. Not really shure of its origin. It was built by a geezer I know. It cant run out of puff and it doesn't kill anything of.

I don't own polluted rails. It's sort of what I do.
I test and service UPS for just about anything, Groundpowerunits for aviation, Inverters and Dieselgenerators and all the fiddly bits asociated. I finally quit. 16.5kHz at high level takes its toll on the ears.

The Sugden has a good chance of being classA - so when you use that does the noise at the drivers decrease at all?
Perhaps there's some confusion over my mentioning noisy power rails within amps. Its the amp's output stage itself creating the noise, nothing to do with the power you feed to it.

Okay, snup, this needs to be a process of elimination: is the issue as bad for digital as turntable, at roughly the same volumes? How much does the distortion alter with volume - increase the volume, and move further away from the speakers; decrease the volume, and put your ear much closer - the idea is that the system volume changes, but the volume you're actually hearing doesn't alter ... ?
Edit: And, as abraxalito is trying to tease out of you, how does the noise vary per amplifier used?

the Sugden stays classA most of the time. Hirage is pure A. The Radford does so many things I like. My first CDplayer (Phillips CD200) went straight into it, no volumecontrol, and driving Ls3/5's in tiny transmissionlines. That was about 1980. Lots of water under the bridge since.
The hum and weird artefacts are just about inaudible when no signal, but its allways worked on. Thats the fun part, because I hear a lot of good music, when trying different things.
I am more or less constantly building speakers for people I know. They are not audiophiles most of them, but they do appreciate decent sound, so I help them. Cheap and cheerful usually, tailored to their needs.

Hum? I never have hum issues, just lucky, I guess 🙂 - plenty of well known solutions for that.
Weird? Probably need a better description here ...
Edit: I was just reminded, the chap up the road, heavily mod'ed gear and DEQX had a hum issue on one listen - I forget the precise solution that time, but it's all about having too many bits and pieces hanging together in some fashion which makes it convenient to keep fiddling with things. I eliminate all the things that make it easy to fiddle, and quite often that solves the problems ....

weird as in periodical interferance hard to track down. Usually transmitters and and grid/powerline disturbance. There is a lot going on between my equipment and the outside world. I am not thick enough to think it will ever be perfect.
But I'm having fun with it and with you 🙂

So, why do you need our thoughts on the matter? You know what the problem is - lack of isolation between the audio circuitry and everything else - just beef that up, end of story ...
this is supposedly about TTs vs Digiloodigilay. Why shouldn't I listen to other peoples opinions ? New things happen all the time. A lot of experienced and superskilled people posting here. I think some of the most interesting and enthusiastic experts in the field of audio reproduction give superb advice and generally gives their valued opinions away to the benefit of everybody. I have no my way or high way. I don't tell people what to do.
Everybody hopefully have their own ideas and there are many solutions to the same problems. I always keep an elephant in the room where I can reach it.
So there
