I don’t spend a lot on line conditioners , I have a AQ 5000 and it is excellent in my system the biggest improvement by far is the dedicated 20 amp line I have using 4 wire Dual ground ,one insulate, one isolated ground on a separate buzzbar
and awg10 Ofc copper wire! And Every connection in my system as well as IEC,and outlets are WBT, or Furutech which btw most people have gold over Brass
the copper has 3 x better conductivity ,which also =S 3 x less resistance or noise
it took me the better part of the year to do this but well worth the effort.
