Is this a strong buy at £45? Yes — against a typical used market median of £95 and a 25th percentile of £51, it lands below the usual low-end of the range, so this reads as a genuine bargain rather than just “fair.”
That makes it an easy shortlist if you want a compact tube-flavoured headphone amp without paying much to experiment. SMSL gear in this lane is generally valued for a small footprint, straightforward setup, and an easy way to add a bit of valve character to a desktop rig; at this price, the main upside is simply getting into the format cheaply. I’d still check the usual basics for a tube amp — working outputs, quiet operation, and whether any original power supply or box is included — but there’s no need to be nervous here if it powers up cleanly.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
