@navyachts, I have 2 dedicated 20-amp circuits for my audio system and both circuits are connected to Shunyata Hydra 4 power conditioner. Shunyata conditioners do NOT limit current, and it is advisable to plug your amp into them. My system is extremely quiet, and the dynamics are off the wall.
Furman Upgrade to Niagra
I remember ready an article some time ago by @erik_squires on 110v power and him recommending these as a good place to start, so I bought a couple of: https://furmanpower.com/product/15a-6-outlet-surge-suppressor-strip/
I recall him saying to use one bank for analogue and the other for digital. Well, I have no analogue gear, so I just use all the outlets as needed.
What would an Audioquest Niagra 3000 or even the Niagra 1200 do for my system over and above my simple power strips, would the large monetary investment be a substantial beneficial to my system over my pair of PST-6s? Thanks.
