Angeboten wird „ATM 3“ von Air Tight als Ausstellungsstück aus der Kategorie „Röhren-Endverstärker“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 2332554630 endet am 26.07.2026 um 15:03 Uhr.
This is a strongly priced listing for an ATM-3, but it is above the usual active market in your database. At €12,500, it sits well over the €10,922 75th percentile, versus a €9,234 median and €7,547 25th percentile, so I’d call it ambitious rather than a bargain.
That said, the ATM-3 is a serious piece of valve amplification with real collector appeal: Air Tight’s build quality, point-to-point style execution, and musical, finely textured presentation are exactly why these amps stay desirable. If this one is genuinely clean and well cared for, the upside is owning a respected, relatively rare amp in good condition; just make sure the tubes, service history, and original accessories are all in order before paying top-tier money.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Air Tight emerged from the vision of Atsushi Miura, a veteran Luxman engineer who joined the company in 1956 and championed vacuum tubes amid the shift to transistors. Retiring in 1985, Miura partnered with Masami Ishiguro to found A&M Ltd. in Osaka, Japan, launching the Air Tight brand in 1986. Their debut ATM-1 power amplifier, a push-pull EL34 design, embodied a philosophy of direct signal paths, point-to-point hand-wiring, and premium components, rejecting printed circuit boards for purest sound.
The brand specializes in artisanal tube amplifiers, preamplifiers with phono stages, and select integrated models, all hand-assembled in small batches by father and son in their Osaka facility. While primarily focused on amplification, Air Tight emphasizes tube-centric purity over broad categories like speakers, DACs, or headphones, prioritizing meticulous construction for uncolored, lifelike reproduction.
Positioned firmly in the high-end niche, Air Tight commands reverence among audiophiles for its confidential, zero-compromise production and reference-grade performance. Legendary status stems from decades of global appeal, from early exports to Hong Kong and China, making it a boutique choice for discerning buyers seeking Japanese precision and tube authenticity over mass-market volumes.
