Feel the itch to try something different, so thinking of selling the HDVD 800. This is the popular HDVA 600 headphone amp paired with an internal DAC. Needs no elaborate description - pairs wonderfully with HD 700/800 Senn headphones. Impeccable build quality. USB/Optical/SPDIF/Balanced and Unbalanced Analog inputs. See complete specs here: http://en-us.sennheiser.com/global-downloads/file/504/548726_HDVD_800_SpecSheet_GB_low.pdf
Not a scratch or mark on it and have the original box with manual. Rating 9/10 by Audiogon standards.
Note: Box dimensions above include additional packing for double box (at my expense). Buyer pays actual shipping and 3% Paypal fees if using credit card.
