Try putting some high quality power cords on it like $1k and up
the Puritan line conditioner may help your problem
The regenerator May or maynot work ,there was a topic on this not too long ago
email Paul at pS audio , do youhave a good dedicated circuit ?
I use a 4 wire awg 10:with dual ground ,a common and insulated isolated ground
on its own buz Barr and ground , go to VH Audio check out his surge protection
and power correction ,under $1k , never use crappy stock power cord .
my brother has a 4000 Accuphase on Audition ,the AQ Tornado HQ,and sourse
made a dramatic difference on amplifier and digital . Also change yourAC wall outlet to a gold copper , the $99 Pangea Copper gold is very good and night and day better then junk that’s built with the house 5x better conductivity which lowers noise,Remove all bottle necks , also on dedicated 20 amp breakers Change every 4-5 years Why becaus3 Copper oxides and corrodes. I bought silver plated Siemens from Germany, before covid and by far the best and Donot corrode, at $45 each ,but now I cannot get them. If you are serious every -4-5 years put in a new Copper 20 amp breaker .wire should be at minimum awg12.
