Cayin iHA-6 Headphone Amplifier - HeadFi

The Cayin iHA-6 is a balanced amp. It takes either single-ended RCA inputs, or balanced L&R 3-pin XLR. However you input, the amp will give you TRUE balanced output. There is a 4-pin XLR port on the front for balanced headphone out. Then Cayin does something weird. They give you L&R 3-pin XLR (if your balanced cable is setup like that) which also functions as a 6.35mm single-ended port. The Left Side produces a Low Impedance output, while the Right Side is High Impedance.
