I own both the Furman pst-8 and the Niagara 1200. Both are great. Garth Powell of audioquest actually designed them both. He used to be employed by furman. There is a pst-8d that cators to digital. I also use the AQ nrg Edison 20 amp receptacle. It’s connected to a 20 amp dedicated circuit utilizing 12 awg romex. My choice of AQ cables include the z3, thunder, and x3 power cords. Speaker cable is the venerable AQ type 4 (2 pairs for biwire). System comprised of Sugden a21 se signature and tannoy legacy eatons.
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.
