I have a pair of HD 650's & a Mini-Matrix for sale, both in good condition-- flakey paint included on headband, (very common on Sennheisers). Everything works just fine, still have original box for headphones but will pack "bombproof" for the Matrix ! I'm moving from apt. to a larger house, & will be taking the "mothballs" out of the 'old Quad Electrostatics (hence my username) so its time for a new home for the cans/dac. This is my first listing here, but I have a sterling record on Ebay as tufdog2 (100%), + a half dozen on Audiogon as I_quadius. Fees & shipping neg, for U.S. only, overseas must pay all costs. PM with any questions or call me direct; 405 627 2729.
