Affordable cables


We all know and can't dispute that SR and other uber expensive cables can do magic with your systems however most of us aspiring audiophiles simply can't afford them. So I would like to hear from some of our colleagues who worked their way up the cable chain what if any cables priced at $100.00 or less made or make the most difference to a system. Interconnects specifically.  Thanks

Actually, not everyone does know this and there is substantial dispute over your claim. Of course, most of those who raise such objections do so based on theory and prejudice, and not on any first-hand experience with the cable. 

 I happen to know how to make a reference IC for close to nuthin if you dear to diy

 
I can DIY if you would be so kind to send any info. 
Thanks
To clear: that is just what I am asking from "experience ". Some unbiased audiophiles can give an honest answer based on years of experience.

IMHO, a lot of the "magic" vs snake oil discussions are system dependent.

When I started , I was very cynical of costly  speaker cables. Then I heard the difference they made in a mid tier system.  

To me, cabling is very important.  Cost justified ?, that's a slippery slope.

One of the biggest cable discussions revolves around premium ether net cables ( its just "bits" ,etc. ) My new streaming system was installed with a basic ethernet cable. Selling dealer said I did not need more.  I had a used mid tier SR ethernet cable ( $350.) sent out on trial. ( just curious)

Guess what --it never went back. The difference was very obvious.

I believe in good  cables especially with good electronics. You don't have to go to top of the line stuff.  Buy used, for sure.  Experiment, no magic bullet and each system will sound different with different cables  Just like speakers--you want to find the sound right for you.
I own 2 systems. The second one consists of mostly dirt-cheap components (for instance, $59, 158..). I took lots of pain assembling the much more expensive first one, especially matching cables to each component, and it sounds divine. What I'd learned from the experience, I applied to the 2nd one. Quite surprisingly, it worked wonders. On some recordings, I like it better even. So I believe even the cheap electronics will benefit from well-matching cables. Please note that I didn’t say expensive, but well-matching.
