Hi, I just dug up an old Pioneer VSX-451 to try and power some Sennheiser HD700's. The receiver is connected to my computer. When my headphones are plugged in, I get a loud hum and white noise. Hopefully this is a simple fix... anyone have an idea as to what's wrong?
Also, would using this receiver provide any benefit over having it directly plugged into an Asus Z87-C motherboard?
