At US$385, this is better than the obvious route of paying near-new money for the same amp, and it lands below the 25th percentile of the recent used market, so it reads as a genuine bargain rather than merely fair. With a median of US$477 and a 75th percentile of US$512, the asking price has real margin in its favor.
The appeal is straightforward: the A70 Pro is well-regarded as a very clean, powerful balanced headphone amp with useful preamp duties, so it suits anyone wanting a serious desktop centerpiece without stepping up to pricier separates. If the unit is complete and working properly, the price looks like a buying opportunity, and the only thing worth confirming is the usual basics—power supply, remote if included, and that all outputs and controls behave cleanly.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
