About the ATH-1 SUT
The Air Tight ATH-1 SUT is a specialized step-up transformer (SUT) designed to work with low-impedance moving coil cartridges. It provides a high turn ratio (1:30 in its 2 Ohm setting, also switchable to 1:15) delivering approximately 29 dB of passive gain. This transformer is engineered to complement Air Tight's reference cartridges such as the PC1, PC1 Supreme, PC1 Coda, and Opus One. The design philosophy behind the ATH-1 SUT reflects a Japanese approach to phono amplification, where tube phono stages typically have modest gain, compensated by high turn ratios in the SUT to achieve the desired signal level. The transformer is built to maintain signal integrity and minimize noise, ensuring a natural and dynamic vinyl playback experience.
