These amps were purchased for a customer who ended up using different speakers than intended and therefore purchased different amps from us. They just came in a month ago and are brand new, factory sealed, and come with full 3 year US warranty from authorized Air Tight dealer and US distributor.
The amps are remarkable - 22 Watt per channel SET monoblocks that are neutral and not lush, and can drive a much wider range of speakers than pretty much any other SET except the Lamm ML2.2. They have the liquidity and smoothness of a world class SET amp without the single digit power limitation or carmel colored sound of 300B type SET's.
The amps are beautiful, and ultra reliable. The amps are also visually stunning. Using them you will find as many reviewers have, that they perform as a 50 or 60 watt amp. With an overbuilt power supply and custom hand wound transformers, you'd be surprised at how dynamic and what kind of bass control, resolution, and frequency extention these amps are capable of.
But above all, they are musical in the midrange, with lovely layering and 3-D palpable image reproduction. Owning a pair of Air Tight 211's is like owning a super expensive Audio Note amp without having to remortgage your home.
Sorry the pictures aren't more exciting, as the boxes are factory sealed. Also available is the matching Air Tight ATC-2 with upgraded potentiometer, truly a world class preamp in its own right, and the ultimate match for the Air Tight ATM 211 mono amps.

After a lengthy review, Positive Feedback magazine concluded:
The character of the Air Tight ATM-211 SET mono amps can be described as hugely dynamic, possessing high definition and notable speed. They throw a rock solid, tightly woven, and excellently described soundstage. A great deal of control is evidentyou might call them strong willed. This is most evident in the clarity, density, and unwavering placement of images on the soundstage, but also in their tight grip over the abundant low-end. Plus, they have some of the high purity quotient and sweet tone associated with the SET topology.
Weighing all of these, the ATM-211s, while residing power-wise in the mid-ground between push-pull and the single-digit wattage SETs, seem closer to the former. The ATM-211s have many of the better qualities of powerful tube or even solid-state gear. They are the best of all the SETs I've tried in terms of dynamics, image stability, speed and bass control. They have little of the usual tube amp downsidesoperation is quiet, there's no tube rush and. while they sound warm, they're not loose (far from it!). Treble is extended, if a little thinner than down below. And like the better tube amps, there is a total absence of any electro/mechanical signature. The 211s credibility was assisted by their real-life, concert-hall perspective. This guy is rather neutral and communicative. If he doesn't capture you on an emotional level, he will certainly entertain you intellectually.
The 22 watts of the ATM-211 were a dynamic shock after listening to eight-watt SET amps. With everything else equal, the 100dB sensitive Hørning Agathon speakers were transformed. Directed by the ATM-211s, they assumed the air of a precision instrument. With the 89dB Kharma CRM 3.2s, their resolving power, and again, the dynamics flabbergasted me.
"Don't be fooled by the 22-watt power rating. Dynamics were excellent into moderately sensitive speakers. If you're used to high-powered tube amps, you'll probably find the ATM-211s are up to the mark. And they'll sweeten the ante with a taste of the magic only SET devices afford."No more need be said than that.
