Hey Sam,
I initially had buzzing issue on my new Saga+ but I've since fixed it. I use a UK 3-Pin socket and it's 230V 50Hz here. There is still a low level hum but no more annoying buzz. I scraped off the paint with screwdriver and grounded the IEC Mains Socket to the case.

Thanks for the encouragement
@WHO23 , there is still hope i see. You said you had this buzzing issue even after the amp was switched off? I noticed that mine does that and it only stops when I take the power cord out (230V, 50Hz). I’ll tear this unit down and document it when I have the time. I have a “lab” in the basement where I work and most of my electronics gear is there.

I was thinking of relocating the PSU part out of current chassis and into a new one. Then feed the Saga with pure, clean and regulated DC. I love the way they made the volume control, I like the form factor of the chassis and the fact that I does have two outputs so I can finally use my headphone amp. This is what I would like to retain, otherwise I’m thinking this as sunken cost of this hobby. As it is now the preamp is 10€ worth of scrap parts (not 400€+ they are asking for it).

I live in Finland. We had the whole house rewired last year when we made a big renovation to our house. I had a dedicated power line installed to my Hifi
So the grounding is up to par. The buzz comes for the speakers.
This is measured with my phone about 20cm away from my speakers (Monitor Audio Silver 100) as baseline noise my tube amp makes at full volume (fully modded Yaqin MC-10L P-P EL34 that was to be turned into a power amp a bit later)...
This with Saga selected and running (also there is a loud “Pop!” when I turn the switch on Saga but it doesn’t show in this.
Granted, this is a very crude measurement done with my phone using iAnalyzerLite on iPhone 7 but it doe show the issue of elevated noise floor and what I think a PSU harmonics.
