Hello guys

For test purposes I get one DVD player box, so everything will go inside ( except trafo), after that, Massimo advise to see if I can make them quiet.

That phono is based around Le Pacific circuit. Salas further improved it. No comparison at all.

P.S. the author stated: This is not a DIY copy of a commercial product
and moreover: use a mid-grade switch mode wall wart power supply for this because they are cheap, easy, and very quiet
No comment!
