My 2 cents worth.
1980's I read brochures from what I could get at stereo stores. Monster cable, interlink 250 $50.00 Straight wire. I settled on these 2 because of cost. Then circa 2018. I moved to Kimber Kable heroes and Cardas cables Iridium and crosslinks. ~ 200.00. The difference was immediately apparent. Clarity,imaging I still have the older cables and I often use them as a filler until new orders arrive. I'm a believer.
