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

I am using on my preamp. My 1.5 meter is not long enough to reach power amp. Plan to get a 2.5m for power amp.

For those who planning to get silver dart speaker cable for biwire-able spk, according to Raymond, Zavfino can make silver dart biwire jumpers but they will be 13AWG.

I am waiting for more update regarding the connector.

“I am using the Dart on my JL Audio CR-1 Crossover”.

Not the best place to use this fine cable, IMHO. 

Due to the length and the cables extreme stiffness, that is the best place in my system.



That was helpful. Don't want an extremely stiff cable. But others in their line are not as stiff, at least that is my impression.
