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.
