You can’t go wrong with Blue Jeans Cables LC-1 interconnects or Blue Jeans’ base speaker cables. Agree on a new TT and cartridge if you want vinyl. The Ortofon 2M Red is a great value. Getting used speakers is smart, but it will limit you to local sellers, since shipping big boxes is so expensive. So if you like what you’ve located already, go for it. But like everyone said, listen, listen, listen. I bet Atlanta has plenty of supply via Craigslist, or maybe search on Facebook for a local audio club. I don’t know if the PS Audio Sprout fits your speaker choices, but It’s a product the company pretty much designed for someone like you, and at $600 you’d get a DAC along with it and avoid interconnects. Really, for $2000 you can get some very good sound. Good luck.
