NVA cube 3s with factory tweeter upgrade, 14 months old, reluctant sale due to MOT bill. White and in as new condition with original box
Compared with the usual used options around this level, £600 is on the ambitious side: it’s above the £589 75th percentile and well over the £405 median, so I’d want either unusually strong condition or a package that saves hassle. It isn’t absurd, but it’s not a casual buy either; the market suggests there’s room to negotiate.
That said, this is a respected NVA piece, and the Cube range is known for a lively, open, very “music first” presentation with good drive and timing. If it’s genuinely excellent, from a careful owner, and ideally complete with any original bits, that pedigree still makes it interesting for the right system. I’d buy it for sound and provenance, but I’d push for a better number unless it’s exceptionally clean.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
NVA, or Nene Valley Audio, emerged from Britain's vibrant hi-fi scene as a specialist amplifier manufacturer founded in 1982 by acclaimed electronics designer Richard Dunn. Based in the UK, the brand embodies the cottage-industry spirit of that era, with Dunn's innovative vision driving its early success until his passing in 2019. Now under Hi-fi Subjectivist Audio Ltd., NVA upholds this heritage through meticulous, handmade production that prioritizes sonic purity over ostentation.
The company's product focus centers on minimalist amplifiers and speakers, including standout pre-power combinations like the P50 preamplifier and S80 power amp. These designs eschew unnecessary frills, emphasizing novel engineering tailored for discerning listeners who value uncolored sound reproduction. While not venturing into turntables, DACs, headphones, or cables, NVA's amplifiers deliver exceptional clarity and dynamics in compact, efficient packages.
Positioned as a niche boutique player in the high-end market, NVA appeals to purists seeking value-driven excellence rather than mainstream flash. Its handmade UK craftsmanship and quirky, sound-first ethos have earned praise as one of audio's best-kept bargains, thriving among knowledgeable buyers who prioritize musical engagement over hype.
