Zero-distortion preamp.
The Earthworks Audio 1022 2-Channel Zero Distortion Preamplifier is based on discrete circuitry designed by David Blackmer. It establishes a new standard of sonic excellence in electronics. This exacting new standard provides frequency response range of 1Hz–200kHz +0.5dB, a rise time of 0.27 microseconds and distortion of less than one part per million (0.0001%), eliminating all possibility of sonic degradation. Like the other preamps in the ZDT Series, the 1022 2-channel preamp is so fast, so clean and so transparent that you don’t even know it’s there. You will hear clarity and detail with the ZDT preamps that is not available in any other preamp at any price.
