About the ATE-2001

The Air Tight ATE-2001 is a flagship stereo tube preamplifier designed for audiophiles seeking exceptional sound quality. It features a frequency response from 5Hz to 100kHz and a total harmonic distortion of less than 0.08%. The preamplifier supports multiple phono inputs including 3 MC and 1 MM, with selectable MC impedance between 3Ω and 20Ω. It employs a sophisticated EQ circuitry with two negative feedback stages and a low-impedance SRPP output stage to ensure low distortion and stable operation. The device includes a separate power supply for improved noise reduction and operational stability, with constant voltage regulators for each valve to eliminate mutual interference. The valve complement consists of 1 x 6X4, 1 x EF86, 1 x 12BH7, 3 x 12AX7, and 2 x 6922 tubes. It delivers a rated output voltage of 2V and a maximum of 20V with an output impedance under 2k ohms. Signal-to-noise ratio is 78dB for phono and 97dB for line inputs. Dimensions of the amplifier section are 400 x 320 x 140 mm, weighing 8.5 kg, with the power supply weighing 9 kg. This model is considered a reference-level preamplifier with a price around and is noted for its build quality and sonic performance.
