Offered is „ATM-2211“ by Air Tight as second-hand device from the category „Tube-Poweramp“ on audio-markt.de - the online market place for high-end. The advert with the number 8280508389 ends on 28.10.2026 at 10:02 o'clock.
Should you pay nearly €28,950 for this, or wait for something closer to the market? Against your own comparable data, that asking price sits well above the €12,200 75th percentile and far beyond the €8,597 median, so it reads as ambitious rather than merely firm.
What makes it interesting is that this is a serious, well-regarded power amp line: these Air Tight monoblocks are valued for scale, ease, and a refined, very “live” presentation that suits revealing systems. If the unit is genuinely clean and complete, the appeal is obvious; just know you’re paying a premium that only really makes sense if this example has standout provenance, low hours, or unusually careful ownership.
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.
