At this time I am moving up in the Grado Cartridge family. I bought this Master Reference Mk.2 High Output model this Spring from an authorized Grado dealer. It was directly shipped to me from Grado. I have been a Grado fan since the 1970's! Its as close to new "broken in" as you would expect. And yes, I have tried some really top brands, including Moving coils, but I return to the natural performance of Grado. It was used in a top quality SME 4 tone arm. As you consider this cartridge, DO take a good look at my extensive all Positive Feedback not only from Audiogon and the US Audio Mart, but on Ebay where its over 1700! I go by the same User name, "thegotoguy01". My buying and selling record started in 2003, but I have been in this hobby since the late 1960's. Because this is a delicate item, I would like to sell this item as a "No Return" transaction. You won't find a more honest seller than me. Paypal and USPS Priority shipping is Free!
