Black rhodium Proto 250 length 3 metre pair with black rhodium banana plugs fitted at both ends cables are in excellent. Condition
This is a strong deal. At £50, it sits dramatically below the supplied comparable range: the 25th percentile is £311, the median £525, and the 75th percentile £689. Even allowing for differences in length, termination, and exact application, that makes the asking price look like a genuine bargain rather than merely a fair used-market buy.
The Proto 250 is part of Black Rhodium’s well-regarded cable range, aimed at delivering a clean, dynamic presentation through careful conductor, screening, and ferrite treatments. At this money, it is an inexpensive way to experiment with a credible enthusiast cable without risking much capital. Check the connectors, cable length, and that there are no kinks, damaged plugs, or intermittent connections, but excellent condition at £50 is compelling.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Black Rhodium traces its roots to 1975, when founder Graham Nalty entered the hi-fi industry as a loudspeaker demonstrator and retailer before transitioning into cable design. The company formally adopted the Black Rhodium name in 2002, consolidating decades of engineering expertise developed under Nalty's direction. Based in Derby in the UK Midlands, the brand represents a distinctly British approach to audio cable manufacturing with a heritage spanning over five decades.
