Used in excellent condition. Includes Power supply. Vinyl is hot these days, and people are discovering (or rediscovering) just how good records can sound. Unfortunately, most new receivers and amps lack the built-in circuitry you need to plug in a turntable. And even if your system comes with a phono input, it still might leave your LPs sounding weak and one-dimensional. The Cambridge Audio 540P solves that problem in a snap. Simply plug this high-performance phono preamp in between your turntable and receiver, and instantly enjoy toe-tapping performance that brings out the best in your albums.
