Musical fidelity M1HPA fed by a micromega MyDAC fed by an airport express controlled by an iPad. The DAC and Airport are hidden away in my nightstand. Only the amp sits up top. Makes for a nice clean look.
i have grado 225i's now that I really like. I've tried senn 650s and akg k702s also. The akg'so are amazing but just too tiring on the ears. I find the grado's to be a nice compromise between the forward akg and the laid back senn 650s.
The MF headphone amp is a pretty fantastic piece. MF has been doing headphone amps for a long time (long before it was in vogue) and I think they really have something special here.
