@nkonor , the Pass XP-15 and 17 have balanced outs, just not ins..That's not quite correct. What defines a balanced circuit isn't really the connector - it's the circuit. A phono cartridge is inherently balanced; that is, it has a separate hot for each channel, a separate ground for each channel, and an earth ground. So when you connect a phono cartridge to a balanced differential preamp such as the Pass, you're providing it with a balanced input even if it's using RCA connectors.
