I need cables for my 2 channel system

My 2 cents. I agree generally with those who say that the best cable for connecting device X to Z is brand S. IOW, one cable very well may not mate well with your gear. I recently went through cables some of which costing north of $600, and below between several components in my system. I slightly preferred Signal Cables which are Copper clad in silver. I have heard the "diode" chatter on line, but it sounded the best in my system. The differences seemed small, but I just upgraded my 801M&W Matrix V.2 with heavily modified crossovers to stock Thiel CS-7's. I was wondering how the Cardis Golden References might sound. With the Thiels the difference was no longer nominal. If you want high quality at a reasonable price, I would seriously consider Signal Cable's Silver Resolution cables. It was actually LAT International's silver/copper cables, where they sent both through a die that pressed them together which made me realize that I generally find that the combination sounds better than either on its own. LAT closed its doors for retirement, and I have honestly only made my own from their hookup wire, so I have never done a toe to toe between them and Signal. Bluejeans is said to be hitting above its weight class, and while I am not wild about their silver cables DHLabs copper ICs are said to be a good bang for the buck. All that said, results in your system, and even between different components may vary! Good luck!

I have never bought anything from the Cable Co., But I have gotten some great deals on Zu interconnects and speaker cables on eBay. None of them made HUGE improvements over the Audioquest ICs they replaced or could best a pair of WireWorld Oasis 7's. Once you get above a certain relatively low price point the law of diminishing returns seems to follow an exponential curve for me. But I only paid what I was willing to gamble and loose for them and I'd do that again, especially for speaker cables. The big fat Zu Libtec cables in single runs were an  improvement over the Auvui Delux 14g silverclad cable I had in a bi-wire set up; but I would have been really disappointed if I'd paid list price.
I didn't start thinking about spending much money on cable upgrades until I'd upgraded my Rotel 100 receiver (an oldie, but goody) For a Primare I32. I know there is supposed to be a synergy between Rotel and B&W, since they share ownership; but the Rotel sounded very capable with my Canton Ergo speakers.
Long story short: I'd look at other things before I spent on cables, were I you.

I did get a hold of someone at the Cable Company and they are going to put together some options for me. I'll make that my first pass and see how it goes. Additionally, I'll be keeping an eye on Audiogon for some deals that might come up. I'm particularly interested in the effects of USB cables on sound (as I am going directly from the MacBook Pro to DAC) and also, if there are some better options for USB-C, though that might not actually matter.
