Condition is unknown, so this one lands as a fair-to-slightly-strong ask rather than a bargain: at US$1,050 it sits just above the US$1,044 median and a touch over the US$1,047 75th percentile, so it is not cheap enough to call a steal, but it is still squarely in the normal used range. For a clean unit, that’s acceptable pricing for a desirable tube headphone amp with a real following.
The HA-2A is well regarded for its full, dimensional presentation and the way it brings body and sweetness without flattening dynamics, which is exactly why buyers keep chasing it used. If it includes the right tubes, remote, and original packaging, that helps justify the ask; if not, the value softens quickly because tube rolling and replacement can add up.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Cayin Audio traces its roots to 1993, when Zhuhai Spark Electronic Equipment Co., Ltd. was established in Zhuhai, China. From the outset, the company focused on crafting audiophile-grade components under the Cayin brand, blending Eastern precision with a passion for musical fidelity. Over three decades, it has evolved from traditional hi-fi roots into a multifaceted player, emphasizing equipment that delivers exceptional sound across diverse price points to democratize high-quality audio.
The brand excels in a broad spectrum of categories, with its vacuum tube amplifiers standing out as flagship offerings renowned for warmth and detail. Its portfolio extends to CD players, speakers, digital audio players (DAPs), desktop systems like the i-series, portable amplifiers, in-ear monitors, and even innovative DACs such as the compact RU2 dongle. Since venturing into personal audio in 2013, Cayin has prioritized portable and lifestyle solutions, including the N-series DAPs, all while maintaining rigorous build quality with premium materials like milled aluminum and walnut wood.
Cayin holds a solid mid-to-high-end position in the global hi-fi market, prized by discerning buyers for its value-driven performance and cultural depth. It bridges accessible excellence with boutique appeal, earning acclaim for tube amps that rival pricier rivals, without veering into ultra-esoteric territory. This Chinese powerhouse continues to carve a lasting niche among knowledgeable enthusiasts seeking reliable, soulful sound.
