@carlsbad2 you went from a copper cable to a digital cable
Assuming you meant 'silver' not 'digital'. Yes, I fully agree that pure silver is excellent for digital for all of the reasons you mention. I want to upgrade my ethernet cable to something similar from WireWorld, but they are quite spendy.
I am also a fan of the OCC metals, my experience is that it makes a difference.
I also agree that silver plated copper is not the best option for audio applications and I generally avoid it. I think this is where silver gets a bad name. I think that solid silver is probably okay and I am currently trying out some https://silversolids.com/ interconnects, but I am still in the break-in period so cannot comment just yet.
