It's a custom Mapletree Audio Design Ear+ HD. Mark took the basic component set, tweaked it, threw out the whole power supply section and designed his own tube rectified supply and then designed the chassis. The chassis, a friggen work of art, is all him, the wood work, the trafos potted in polished old film containers, etc. I guess he had the plate fabricated but he did the cad layout drawings for it. And you should see the wiring, it's just unbelievable. Mark (Voodoo) is one of those people that sets the bar so high for the rest of us all we can do is look at it and go, "man, my stuff looks like crap."
