Connected to my high quality Pioneer Elite A/V Receiver with headphones on the RCA jack and it works, but I have a very low input compared to every other input on the unit, including an RCA headphone cable connected to my Android phone. I have to turn the volume up so much that I get kicked out of the living room and get a headache if I forget to turn the volume down before switching the source. I like the impedance of the signal, maybe I'm doing something wrong, but it's not suitable for my needs.
