There's some pretty sweet hifi gear out there that make CD's sound pretty damn awesome. Audiophile, expensive shit. There will be a market for CD's in that crowd for sure for a long time. You don't invest a couple grand into something you're just going to "give up on." BTW, I once heard that playstation 1's were/are much sought after by the audiophile crowd for the "better than most" sound quality. Personally, I love it when I buy a record and get the free cd inside to listen to in the car. The Truckers do it all the time. I've got the cd with Wilco and WSP and a few others too. You almost always get a free digital download with most new albums. I'd say....to sum up.... keep the cd's that are originals, chuck the burnts unless they're great live shows, hard to find. KEEP ALL YOUR DEAD.
