DC blockers, mains regenerators & balanced mains transformers
After discovering I have DC on my mains (probably down to the heat pump or reversible air con) I am wondering what would give the best improvement in sound - if any.
I have a DC blocker on my power amp to stop transformer hum. Is it worth adding one to the pre amp and CD player? There is no hum from the pre amp.
A mains regenerator would solve the DC as it converts AC to DC and back to AC.
Would a balanced mains transformer would still create hum? I was looking at an Airlink 3000VA but if I understand correctly, this will likely hum due to the DC offset on the mains.
Can anybody share the benefit of their experience of mains regenerators compared to balanced power supplies? It all seems a bit of a gamble if it will improve the system sound not, so part of me is saying to forget playing with mains accessories and just enjoy the music.
