⭕ Close to MINT pair of McIntosh MC3500 tube amplifiers, the most glorious, huge, sweet tube sound, with a soundstage and clarity of detail unsurpassed by any vintage tube powerhouse, CONSECUTIVE serial numbers, and ORIGINAL BOXES included. I had 4 Marantz 9s when I acquired these; after comparing the richness of sound and detail, I put them away the Marantz without hesitation! The 3500s make the 9s sound small and strident, lacking a dimension of soundstage and depth. I was blown away by the difference! Shipping/ pickup. This pair is in amazing original condition. Plug and play condition
