I don’t like the “horrid” Chinese Rega PSU’s either.
They get hot and are cheap crap build.
Even they are Rega approved I believe it could be done better.
OK for the entry level decks it makes sense but not for P6/P8.
I’d certainly get alternatives for home demo if I was a P8 user.
But am waiting for the hopefully upcoming Planar 12 ( or P50)
