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

@derekw_hawaii As opposed to the Silver Dart (by the way I really like Zavfino products) I highly recommend you take a look at the Vouge Audio power cord including their interconnects and speaker cables. Currently on sale and I have been extremely impressed with the products, fast turnaround time, and free shipping USPS. Very helpful if you have questions, open to emails or phone conversations. In my opinion a hidden treasure, I compare them to my Grand Lavricables 5N Silver cables.
