There is a lot of good product on the market, and a lot of not-so-good product as well. How does one choose?
The recommendations here can lead you to becoming dizzy. Nobody means harm, it's just that there are so many choices.
If it's a one-brand way that you wish to do your system than I wholeheartedly can recommend Audioquest. That's what I did and couldn't be more happy. Go to their website and look at the left side column for categories. Near the bottom you will find a PDF for the 2020 Retail Price Book (unless they have already replaced it with the 2021 edition). The first pages tell a great story about their design philosophy and offers quite an education on metals, extrusion, and other materials that make up their cables. Each product category also has a nice story about the respective products and models. Even if you choose a different brand, you will have learned quite a lot from reading the Audioquest information.
Best to you, I hope that you land on products that are satisfying to your needs.
