One of a kind. Hand made. Yuan Jing "Black" board (better sounding) TPA3116D2.
Very dark brown, nearly black, gloss metallic enamel painted aluminum chassis.
Wood burned flea logo in real walnut veneer. Solid, machined brass volume knob adorns a VALAB brand stepped attenuator. The Valab attenuator features Japan made KOA 1/4W 1% 25ppm precision resistors. Only two of these audiophile resistors in the signal path. The most open and revealing of volume pots I've ever used.
