Why not use the Mundorf M-Lytic Bi-polar? Those are really good and have low ESR
Do
Is there anything wrong periodically with your mains quality maybe? So your system comes and goes over a few weeks?
Siberia - maybe a few very good result ion Jpegs would help look for any nasties.
Is there a cap across the AC, like .0033 to 0.1uf X or Y rated?

Those comes and goes always had a reason that I or we have discovered eventually. Bad grounding, badly soldered wire, etc... Mains quality never played a role on it.
How do I check the "going south" thing?
These are most recent measurements:
VDC -10.30; + 10.24
VACin -16.60; +16.72
DCout -1.6; +0.9
Here are some pictures.

I could additionaly make every angle you ask.

Do you have different shunt resistors to try?
While those naked Vishays are the best for direct signal path I don't think they're as good for shunt... you need something that sounds bolder like PRPs or carbon films IMHO.
The way you checked is OK. Shows your mains are high enough to give margin. Regarding the pictures, maybe its better you solder the in/out wiring directly under the PCB on the connectors pads? Since you say it was always a contacts or good grounding thing, maybe worth a try.
Dario, I've tried carbon films and other resistors in those and all critical positions previously. You are right, carbon films sounded bolder. But I prefer "nakeds" for their uber transparency. My problem is on bigger scale than mere tonality...
I wonder could it be heard on the file I have attached?
Salas, I've just followed your advice. Signal wires straight to pcb under it. Same sound.
I wonder also if could it be an amp related problem. For example bad amp rca connection?

If I had to describe what sound I'm getting, I would say it's all perfect except that somebody turned down low region knob on invisible eq.
Weird stuff. Since its about anemic low region you are right to suspect possible power stage related issues also. A DC line stage why to periodically cut on bass if all healthy its beyond me. You need some tech tests and related equipment data so we can really say for that system as a whole. Or some luck with trial and error on connections and parts.
I presume thats supply voltage for the rails and DC offset (signal) at the output, not exactly the most intuitive way to write it
Tx secondaries: 16.60V; +16.72
-1.6; +0.9 is Dc offset on output.
Sorry, if it's counterintuive.
On my suspicion list one power amp rca which feels to have a looser connection then the other. I can tighten the plugs to grip well, but I wonder could it create the problem where "the nose" of connector it's not touching properly the conductor inside the socket?
I finaly managed to complete my Tea-bag Kit Dcb1 build.
The kit was very easy to use, and everything seems to work also!
I do have one measurement that is kinda well... Weird.
My Vout+ and Vout - are almost the same. 9.95V and 9.94V. What I read in the manual the Vout + should be higher then Vout- ? Is this bad?
The rest of the measurements:
Voltage drop on the power resistors: 1.764V and 1.861V
The output: Right 1.6mV dc
The output: Left 1.8mV dc
Led string -9.31V and +9.32V
I am using btw a 12v transformer, (for testing) would a 15 volt one be preferred?

In Hypnotize both rails tracking close is the right thing. In Mezmerize a bit apart is the right thing. So yours is OK. To tell if your OK with your Tx on your mains, give us the DC in value. You can measure it under one of the big filter capacitors.
