This is a "mint-minus" pair of the most desirable version of the Quad ESL63 in perfect working condition with upgraded input filter components. I don't know what else to say; you won't find a nicer or better sounding pair of ESL63s. Serial numbers are consecutive, indicating they were born as a pair from the factory (Q034573 and Q034574). The wood panels are flawless, tops and bottoms. I do not have shipping cartons for these, but I would negotiate the cost of having some cartons built for them. Buyer pays shipping. Please call with any questions: Lew Markoff; 301-537-5813. These are available for audition in my home in Bethesda, MD (just outside Washington, DC).
