Against a current new price of about £1,295 from a UK pre-owned dealer, this asking price is fair and essentially at market for the used Phonitor X, sitting just under the £1,297 median and right on the £1,296 25th percentile. It is not a bargain in percentile terms, but it is a clean, sensible buy if the unit is properly described and in good working order.
That still makes it appealing because the Phonitor X is a seriously capable headphone amp: studio-grade build, lots of power, and the crossfeed/speaker-angle tools that make it especially good for judging mixes and giving headphones a more speaker-like presentation. At this level, the main upside is getting a high-end, German-made unit for roughly the going used price without taking much depreciation risk, so if the condition is genuinely good and the accessories are complete, it looks like a strong enthusiast buy rather than a speculative one.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
