My system is exclusively XLR, except where it’s impossible—like my turntable and tube preamp, which use RCA. For cables, I use Mogami with Neutrik connectors. You can build or buy them pre-made; the pricing is very reasonable.
My thinking is simple: if it’s good enough for professional studios, it’s good enough for me. There’s no need to spend $4500 on XLRs with carbon fiber shells and silk-wrapped cables. I’d rather use well-engineered, proven cables with top-tier commercial-grade connectors—nothing flashy, just reliable and built to perform.
