The Cayin N3 Pro is a versatile high-resolution digital audio player combining dual AK4493EQ DACs with both vacuum tube and solid-state amplification.One of its key features is the pair of genuine JAN6418 vacuum tubes, offering two selectable sound signatures: Triode and Ultra-linear, alongside conventional solid-state output.The N3 Pro can also function as a Bluetooth DAC/receiver, allowing wireless audio streaming from a smartphone or other compatible device through its high-quality audio circuitry.Key features:Dual AK4493EQ DACsGenuine JAN6418 vacuum tube amplificationTriode, Ultra-linear and solid-state modesBluetooth 5.0 receiver and transmitter (LDAC, UAT, AAC, SBC)USB DAC functionality for computers3.5mm headphone output with tube and solid-state modes4.4mm balanced headphone outputHi-Res PCM up to 32-bit/384kHz and native DSD256microSD playback and 3.2” touchscreenCondition and accessories:Mint condition, used only a handful of times at home, with no visible signs of wear.Includes the original box, complete original accessories, official green Cayin protective case and genuine Cayin dust plugs.Fully functional and carefully maintained.
New, the Cayin N3Pro sold for about USD 479, so USD 387 is a reasonable used price—roughly 81% of original retail. It is not an obvious bargain without a strong condition/accessory story, but it is comfortably below new pricing and fair if the unit is clean and fully functional.
The appeal is substantial: selectable solid-state, tube-triode, and tube-ultralinear outputs give it unusual tonal flexibility, while balanced 4.4mm drive, dual AK4493 DACs, USB DAC functionality, Bluetooth, and DSD256 support make it a genuinely capable player rather than a novelty. Tube mode is single-ended only, and the platform is older with no native streaming apps, so confirm battery health, screen/buttons, tube operation, charging, and the included case/cable before buying. At USD 387, a complete, well-kept example is worth serious consideration.
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.
