A quality transformer
.. but due to voltage drop it cannot feed the Raspberry Pi4 with my stabilizer module, I had to use a DC-DC step-up converter after rectification/stabilization. With that, everything is fine now. When looking for a Raspberry/DAC based transformer, choose a higher voltage one. Apart of this, quality is really top notch, the transformer is absolutely silent, quality work.
