Stereo Power Amplifier (KT88)

“In tribute to the ancestors who created masterpiece amplifiers, wishing to be the same for the modern era”.

AirTight released the original ATM-2 in 1988 with this statement. This KT-88 based push-pull power amplifier was released when vacuum tube amplifiers were considered to be obsolete, old fashioned products on the way out, rapidly replaced by more modern solid-state designs. Completely ignoring the trends of the day, AirTight released this hand-made masterpiece and it instantly became a symbol of superior sound quality in an era dominated by convenience and escalating power outputs. In fact, the ATM-2 became the longest running model in AirTight’s history.

The new ATM-2Plus is a completely new internal design while externally it has remained true to the original’s unmistakable style and proportions. All the circuitry, including the 1st & 2nd amplification stages and internal layout has been redesigned and updated. The plate voltage of the KT-88 tube has been lowered while keeping output power for longer tube life as well as stable operation of the amplifier. For the optimum operation of KT-88/6550 tubes, 6CG7/6FQ7 tubes were incorporated for wider amplitude and lower distortion. AirTight also redesigned a ‘negative feedback loop’ to optimise damping factors to match modern speaker designs.

The Output Transformers are a critical component for a power amplifier of this design. The ATM-2Plus implements brand new original Tamura design low impedance 100W class large output transformers to allow plenty of effortless bandwidth. For the important role of Power Transformer, AirTight decided to use a custom-made hand-winded/ paper wrapped transformer made by Japanese craftsman for a clearer and bigger sound stage. These custom-made transformers account for both the incredible sound quality and the cost of this amplifier.

The design aesthetic of the ATM-2Plus pays homage to its predecessor, however under the skin it features a new fastening & grounding system. Keeping with AirTight traditions, no printed circuit boards are used. All the internal wiring is high quality point to point incorporating a new safety circuit to protect the amplifier from output tube failures. All ATM-2Plus amplifiers are hand made by AirTight’s experienced craftsmen at the AirTight factory in Takatsuki, Osaka.

When high end amplifiers are discussed, how often can you really use words like ‘heritage’, ‘lineage’ or ‘pedigree’? For the last 32 years, the artisans at AirTight in Japan have been building, listening, refining, improving and evolving a classic design. How many products can you thinks of that have had that much time, patience and energy devoted to their development? The ATM-2Plus is an updated, thoroughly modern hand-made amplifier with ‘coach-building’ attention to detail. It has an uncanny ability to produce music with a natural tone, an inner glow that infuses every note, every lyric and passage. When you have transcended the need for bells and shining lights and you simply want pure, unadulterated musical enjoyment, the ATM-2Plus beckons.

Image HiFi Magazine Germany, Ekkehard Strauss, 2020

While listening to Max Bruch’s Violin Concerto No.1 in G Minor… you inevitably end up with a big lump in your throat – such is the ‘unbelievability’ of the sound. Heifetz’s virtuoso playing on his Stradivarius is so captivating you almost forget to breathe… If your focus is on playing a wide variety of music you can put an end to the search for an amplifier once and for all. With the ATM-2Plus, Air Tight proves once again that, in the end, nothing can replace an outstanding developer’s ear – the biggest compliment that I can give to this small manufacturer in Japan.

If we care about racism and white privilege, what should we do?
Format: Kindle
One hundred and fifty-two years ago, slavery ended in the United States. And yet the tentacles of that time touch lives every day, all these years later. What can be done to make things better? Michael Eric Dyson, a sociology professor at Georgetown University, and an ordained Baptist minister, suggests that white people who care about the lives of black people should make individual reparations. In his book, Tears We Cannot Stop …A Sermon to White America, Dyson says, “{Black people} built a legacy of excellence and struggle and pride amidst one of the most vicious assaults on humanity in recorded history. That assault may have started with slavery, but it didn’t end there. The legacy of that assault, its lingering and lethal effect, continues to this day. It flares in broken homes and blighted communities, in low wages and social chaos, in self-destruction and self-hate too. But so much of what ails us—black people. That is—is tied up with what ails you—white folk, that is. We are tied together in what Martin Luther King Jr. called a single garment of destiny. Yet sewed into that garment are pockets of misery and suffering that seem to be filled with a disproportionate number of black people.” The book, unlike Dyson’s other scholarly works, takes the form of a worship service, and uses the concept of an extended sermon, or jeremiad, to lead the reader through confession, repentence, and redemption “through the long night of despair to the bright day of hope.” In Dysons’s view, “whiteness is a problem to be struggled with,” and his book is of inestimable value in grappling with the struggle. The book speaks at length of police brutality against black people, and fervently tries to create empathy in white readers. It includes an extraordinary bibliography of books which give insight and voice to black history, oppression, pain, achievement, and lives. And it speaks of reparations, and our responsibility as white beneficiaries of an unequal system, to take concrete actions to right the wrong, the change our country and the lives of our black sisters and brothers and their children. Dyson is imaginative, and has many suggestions for how an individual or group “I.R.A.”—an Individual Reparations Account. We could buy books for black college students, overpay our black accountant or hairdresser, pay the black person who cuts our grass double the amount on the bill, give to the United Negro College Fund, and more. He suggests that faith groups consider giving 10% of their revenues to a church I.R.A. In an interview in the New York Times Magazine, Dyson says, “If the sermon ain’t making you a little bit uncomfortable, it ain’t effective. Look, if it doesn’t cost you anything, you’re not really engaging in change: you’re engaging in convenience. I’m asking you to do stuff you wouldn’t ordinarily do. I’m asking you to think more seriously and strategically about why you possess and what you possess…..you ain’t got to ask the government, you don’t have to ask your local politician—this is what you, an individual, conscientious, ‘woke’ citizen can do. I have read many—though surely not all—of the books Dyson recommends. I have grappled with white privilege as a mother of black children, a fighter against apartheid, a civil rights activist, a human being. I have never read anything which more cogently offers “woke whites” a path to being a part of the change. I urge you to read Tears We Cannot Stop …A Sermon to White America, and to take your place in the pantheon of people who help this country grow beyond its racist past.

Powerful and especially so read aloud by the author.
Format: Audio CD
Hearing this powerful book read by Dr Tyson made it doubly understandable and enlightening. I needed to hear the experience, hurt and anger expressed so incredibly honestly and with the power of his emotion. I saw the CDs here at a reasonable price and I am so much more aware hearing rather than reading this book. Dr Tyson teaches powerful historic and current systemic racial experience such as every white person will do well to encounter. If you want to learn more than you already know, listen to these CDs on Black experience from Dr Tyson. Could be disturbing to anyone who does not want to learn the truth he teaches. It’s so packed with truth I will listen to it more than once more. Thank you, Dr Tyson.

brilliant, painful
Format: Hardcover
Timely, provocative, brilliant, painful, and, ultimately, a very necessary step toward authentic national healing and transformation. As a white, long-time fellow traveler, I am so grateful that Dr. Dyson has answered his calling to lead us toward redemptive justice with truth, decency and love--albeit, at times, necessary tough love. I am in my third read already and learning more and more each time. Dyson's sermon serves as an exceptional read for believer and non-believer alike as it offers a framework and lexicon for us to engage with one another as we work our way through ongoing racially turbulent and polarized times. I am not a critic by trade so I will leave the professional analysis to the experts. I am a K-12 educator and seeker of social justice. I found this work both accessible and challenging in the best of ways. In my daily work, the evidence of the invention of whiteness, white innocence and white fragility and their pernicious impacts are ubiquitously abundant such that Dyson’s claims simply cannot be denied. Dyson’s sermon is not always a comfortable read. That’s the point. It is a workout for the soul and psyche that results in the growing pains necessary for personal and collective liberation. Thank you, Rev. Dr. Michael Eric Dyson, for opening your head and heart so broadly and deeply there is room enough for all of us in this racial healing process. The writing of this book is the ultimate act of truth and forgiveness. You have entrusted us with your most profound insights, personal experiences, and extend a vulnerability that humbles and arrests me. As you shared in a recent interview, "your trust in us grows out of forgiveness and the demand for truth for which is stands on, and the love it seeks to extend". Amen! I am in!
