There is a company here called TSI, they make voltage controllers using IGBT drives, no relays or triacs.
They are the Asia Pacific regional center for an American company, and tend to use top brands like Fairchild in their products.
Response time is 15ms, and output variation is +/- 1V AC at 220 V.
Look for something like that, I think they will have competitors as well.
No ties to any seller.

All this thread, that I read carefully, didn't help me much as I am technically completely out !
My system is made of few components supplied with DC low voltage (throught some kind of brickwall transformer), only the amplifier is straight on the 230Volt.
What should I do to clean the system, supposing anything is worth doing ?

Well the obvious step would be to check and measure the low voltage DC PSUs if they are SMPS with forthcoming high noise and EMI.
Then don’t look at “names” and build linear PSUs. Make sure you build PSUs that can deliver the required voltage and current. Focus on low noise, low loss, low heat and let them have true power on/off switches.
One can clean up the AC side but what if the adapters themselves create most noise!? Post SMPS filters are nice but they won’t improve EMI feedback at the mains side and let’s say average SMPS reliability of audio gear is a parameter too.
If you are satisfied after this adventure you can have a look at the AC side of course. Or you just do both as it pays off.
