OKay okay. The 5.1 headphone thing was a bit of a joke. All the 5.1 headphones I have seen are way below 16 channels of B22 goodness.
I am actually building four balanced B22s for myself and a couple other head-fiers. Using two sigma 22s for power with the off board heat sinks for better heat dissipation. Still a lot more work to do but all the tedious part soldering is done. I think I am a bit loopy from all the flux vapor
