£200 is a fair asking price, sitting just above the £195 median and at the top of the typical £189–£200 range for recent examples. It is not a bargain, but it is defensible if the unit is clean, complete, and working properly.
The MK III remains a well-liked OTL Class-A valve amplifier, particularly with medium- and high-impedance headphones, where its smooth, spacious presentation and useful tube-rolling options are genuine attractions. It also doubles as a preamp and offers selectable gain, adding flexibility to a modest system. At this price, confirm that both pairs of tubes are included, the gain switches work, and there is no channel imbalance, hum, or scratchy volume control; fresh valves or missing accessories would make £200 less appealing.

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.
