Favorite cable brand.

I use all Amazon Basics 

Started back in the early ‘80’s before all the whiz bang stuff was available, never bought into the hype. I do like good looking cables though so I always made my own. Just found a receipt where I paid 25 cents a foot for pure copper 16 ga 8 wire braided speaker wire.......in 1990.

I have had a lot of BEL, then the mid-price Cardas.    Recently upgraded my balanced interconnects and speaker cables to the designs of Colin Wonfor, sold by ABCaudio in the U.K.    Colin was the original designer of the Telerium Q cables.   
I am totally floored by the recent upgrade.  So impressed that I’m considering buying EXTRA cables for different speaker set ups.   

Tara Labs, Purist audio design

Currently, I am using cables from Down to Earth Cables, I love that I can select not only the wire I like but also customize it as well with the options of tech flex, as well as a variety of Banana plugs, Spades, or Pins.  
Their Interconnects are also well made and the Power cables have been a game-changer -  especially the Silver Wattgate plugs, my soundstage is incredible! and all my cables match!  Might not be important to some, but I love it (Snake is my current favorite.)
