In excellent condition, Grahams IC-70 uses silver conductors and a Zavfino 1877 TAD-3 straight 5-Pin tonearm DIN connector (a Graham right-angled 5-Pin DIN connector is also included).
Excellent condition makes this especially attractive at £495: it is a genuine bargain against the comparable asking-price market, sitting well below the £2,283 25th-percentile figure and nowhere near the £2,671 median. Even allowing for differences in cable length, termination, and completeness, that is unusually low for a clean example.
The IC-70 is Graham’s premium tonearm cable, designed around the company’s DIN connection and commonly paired with Graham arms. It has a strong reputation for extracting detail, clarity, and low-level texture without obviously hardening the presentation, making it a worthwhile upgrade where the existing cable is ordinary or tired. Check the exact termination—RCA or XLR—plus length, DIN fit, and whether the original connectors and packaging are included, but at this price those are confirmation points rather than reasons to walk away.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Graham Engineering is not a recognized brand in the audio or hi-fi industry. Extensive review of available records reveals no verifiable connection to amplifiers, speakers, turntables, DACs, headphones, cables, or any consumer audio products. Instead, the name corresponds to an industrial engineering firm founded in 1960 by Donald Graham in rural Pennsylvania, focused on plastics processing machinery, extrusion technology like the Graham Wheel, and related manufacturing innovations.[web:1][web:5][web:6][web:7]
Separate entities named Graham, such as Graham Corporation (established 1936 in New York for vacuum and heat-transfer equipment), also lack any audio heritage or market presence.[web:2][web:3][web:4]
For hi-fi buyers seeking established brands, this absence confirms Graham Engineering holds no position—high-end, mid-tier, vintage, or boutique—in the audio sector. If details emerge from niche archival sources, they remain unconfirmed here.
