Up for sale is a time-capsule grade, 10-foot pair of legendary Monster Cable M-Series M1.4s Biwire speaker cables. This set is in pristine, near-mint condition and includes the highly sought-after original hard-plastic protective briefcase, factory warranty documentation, product booklets, original stickers, and integrated factory velcro organizational straps. The cables feature clean, high-grade factory-terminated banana clips entirely free of corrosion, oxidation, or fading. The outer grey protective jackets are firm, pristine, perfectly legible, and free of any typical sticky degradation or cloudiness common with vintage rubber. Built with Monster’s patented Magnetic Flux Tube and Time Correct Windings, this heavy-gauge audiophile set is a true plug-and-play addition for collectors looking to extract full clarity and wider staging from high-end vintage speaker configurations. Will be meticulously packed inside an additional shipping box to preserve the structural integrity and cosmetic finish of the original factory briefcase. Shipped fully insured.
