Ambitious asking price at USD850—way above the typical used market for Infinity Black Widow tonearms with a Grado G2.
Our recent comps from 13 USD listings peg the median at USD164, with the 25th percentile at USD75 and 75th at USD180; this one's over four times the norm, even if condition's strong. Without model specifics or photos, it's tough to justify unless it's a pristine rarity, but expect negotiation or a pass unless you're chasing nostalgia.
Buyers, verify the tonearm's gimbal bearings for play or rust—common wear on these vintage Infinity pieces—and check the Grado G2 stylus for hours used, as diamond wear kills tracking fast. Insist on original mounting hardware and counterweight included; missing bits tank value quick. Test VTA adjustability too, as misalignment's a frequent gripe.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Infinity emerged in 1968 from a Woodland Hills, California garage, founded by Arnie Nudell, John Ulrick, and Cary Christie. Driven by Nudell's passion for classical music and innovative engineering, the trio launched with the groundbreaking Servo-Statik speaker system, featuring electrostatic panels paired with a servo-controlled woofer derived from defense technology. This American brand quickly gained traction through pioneering materials like neodymium magnets, mylar diaphragms, and polypropylene cones, establishing a legacy of pushing audio boundaries before acquisitions by Electro Audio Dynamics in 1974 and Harman International in 1983.
The company has long focused on loudspeakers as its hallmark, from early electrostatic hybrids and the iconic Reference and Kappa series to later EMIT and EMIM drivers in the 1970s. While primarily a speaker specialist, Infinity has ventured into home and mobile audio, including amplifiers and systems under Harman ownership, now part of Samsung since 2017. Turntables, DACs, headphones, and cables remain outside its core expertise.
Positioned as a mid-tier powerhouse with high-end aspirations, Infinity commands respect among knowledgeable buyers for its vintage collector appeal and enduring innovations. Once a darling of audiophiles for transparency and dynamics, it now blends accessible performance with Harman reliability, appealing to those seeking proven heritage without boutique exclusivity.
