What sets ATI’s Class D amplifiers apart from the pack isn’t just their use of Hypex N-Core® modules — it’s the way Morris Kessler integrates them. Each AT522NC amplifier features a proprietary ATI input buffer stage that ensures maximum signal integrity, tonal neutrality, and musicality. Most Class D amps rely solely on the off-the-shelf module, but ATI adds its own engineering layer to elevate performance into true high-end territory. Pair that with a massive linear power supply — instead of the lightweight switching supplies found in competing Class D designs — and you get rock-solid current delivery, tighter bass control, and the effortless dynamics that ATI amps are famous for. This unique combination of ATI input stage linear power is why these amps sound more like the best Class AB designs, while retaining all the efficiency, low heat, and compact size of Class D. WHAT THEY’RE SAYING “Powerful dynamics, uncolored sound, and extraordinary value… I liked these ATI amps so much I bought them to replace my long-time reference Parasound A 51.”— David Vaughn, Sound & Vision “Solidly built amplifier based on Hypex NC500 modules with ATI’s execution behind it. Overall, I can recommend the ATI AT522NC stereo amplifier.”— Amir M., Audio Science Review “The AT522NC woke up my Revels, with big dynamics and room-shaking bass. This is not the case of Class D being dark or lacking bass.”— Rich B., Audioholics “Fully differential ‘true balanced’ construction is rare even among high-end amps. ATI uses it to cancel noise and improve speed — a real engineering refinement.”— Brent Butterworth, Home Entertainment & Design “Everything I needed in an excellent pair of amps at a great price, made in California. Quality construction, careful engineering, and thoughtful features. Well worth the money.”— AVS Forum Reviewer More Power. Less Heat. Better Sound. That’s ATI.   *FAQs
