Many nice gents in this site, highly reputable common folks audiophiles like @lalitk @wig and others have mentioned these, so it’s probably time to create a specific thread on Zavfino, a direct sales cables company based in Canada with presence ‘ distributors in US, also direct:

I took the advice of these folks with a power cord, the Prima MK2

I could not be happier with this cord, something that would easily cost $2,000 or even $3,000 from other better known cable makers. It’s outstanding, for about $500. Absolutely amazing build, and packaging too. It sounds great, very quiet. I am sure the cheaper PC, the Majestic at $390 is very good too: 
I now have the Prima speaker cables on my way. Call me “sold”.

No BS, truly top quality cables company that flies under the radar. Very affordable too. Take a look. No relation to the company, just a happy first time customer, thanks to my Audiogon friends here
Not yet @kimurastanley.@kimurastanley.I received two silver darts power cords yesterday, but I am letting them break in somewhere else (not audio).

I currently have and use the following:

One Prima MKII power cord
Prima MKII speaker cables (I use two runs / pairs for biwire)
Silver Darts XLR interconnects

As I mentioned above on my previous post, I am gradually getting there, full loom Zavfino. It will be a combination of Silver Darts & Prima when all is said and done
“The improvements are cumulative, and I believe mostly due to the full loom concept.”

@thyname, Exactly!
The fusion XLR still on the way. Can’t wait to try it. 
Wondering what is the difference bet Prima and silver dart, I am considering that  too.

Well, I received the Fusions on Fri., I put about 11 hrs. on them so far. These are the first cables I’ve tried, that went thru many changes in sound in my system. Zavfino’s website states; their fabrication prosses, equals 30 to 40 hours of break in time. So that gives me 40/50 hrs. on mine. I’m hoping that they will settle in around 20 hrs. of me spinning vinyl. So far I’m I’m impressed after the 9 hr. mark, I could only imagine the sound when they're fully broken in! TBC
