Recent comparable listings put the typical used price at £110, with £89 at the 25th percentile and £176 at the 75th. At £130, this is a fair buy rather than a bargain: comfortably above the median but still well inside the normal market range, assuming it is complete and working.
The MK III remains a well-liked entry to valve amplification, particularly with higher-impedance headphones such as the Sennheiser HD600/650. Its variable gain, preamp output and tube-rolling options add useful flexibility, while the OTL Class-A design tends toward a fuller, warmer presentation. Check that all four tubes are fitted, the channels are balanced, and there is no hum or crackle; tube noise is a common age-related nuisance. With healthy valves and the original power lead, £130 is a sensible enthusiast price.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Little Dot Audio is a Chinese hi-fi brand best known for its tube electronics, with early community references going back to the mid-2000s; the exact founding year and founder are not clearly established in the available sources, so I can’t verify a more precise origin with high confidence. It has long been associated with direct-to-consumer sales and a pragmatic, enthusiast-driven approach rather than a heavily branded international presence.
The brand’s core focus is headphone amplifiers, especially tube and hybrid designs, and it is also mentioned in connection with related amplifier variants across portable and desktop formats. In practice, Little Dot is most often discussed for affordable tube amps aimed at headphone listeners who want a first step into valve sound, with models such as the MK II, MK III, and newer balanced/hybrid iterations drawing the most attention.
In the market, Little Dot sits in the niche value segment: not high-end luxury, but not disposable entry-level gear either. Its reputation is built on strong price-to-performance, tube-rolling appeal, and solid build quality for the money, making it a familiar name among budget-conscious enthusiasts and vintage-sound fans rather than mainstream buyers seeking a broad product catalog.
