I have various powerline stuff in my setup.
I would agree the Porter ports are a good deal at $35 each.
Many of the various specialty ones that range from $50 up to $300 are more tricked out, with special plating, and materials. But the porter is just a basic good outlet. I do NOT own any Porter Ports, I have a pair of similar priced cryoed outlets from someplace? they also were $35. each.
I then have a mountain of conditioners, and cords.
My Furman REF20i for the Bryston 4B-SST2 am and all the video and plasma TV.
Then a PS Audio P600 i just bought used to replace a Monster 7000SS, I wantd it beccause it can be set to output an A/C at various freqencies besides 60 cycles. So right now I have it set to regenerate the A/C at 110hz. That conditioner is mostly for the digital stuff.
Then i have a PS Audio PPP I use in the "Multiwave" mode for the tube stuff.
All my cords are Pangea, Either the 9 gauge, or the 14SE.
I use the 9 gauge on a few items that are not big electricity users if I want more low frequency emphasis, and the 14SE if i want the clarity.
The big thing lately was sticking Quartz crystals around the A/C stuff. Then pigtails off the neutral on the A/C incoming lines.
I just have to agree the biggest change is to go from the stock cheap wall outlet to a better one. Even if all it is is a Pass & Seymour $3 Menards one.
I am more of a conditioner person than a powercord person. For my Thousand dollars i want a near-hundred pound chunk of stuff. Not a little extension cord!!
