FWIW, I recently home demo'd a Torus Tot MAX Isolation Transformer with great results. The gent who had the demo unit before me ended up ordering one to replace his PS Audio PP 12.
Both my digital side (DAC/Streamer and Master Clock) and analog side (Phono Pre) benefitted with a blacker background, more detailed, deeper 3D soundstage, and a deeper, clearer low end. Also had my Preamp on the Torus.
I ended up ordering and inserted the Torus RM 15 (color, dimensions, more outlets, built-in SMSS).
l also have a dedicated 20A line for the audio system and keep my amplifiers plugged into the wall; haven't yet tried them into the Torus RM 15.
Anyway, you may try a Torus if you can demo one...
