Details
The core of this sophisticated device is a three-stage active RIAA equalizer circuit featuring the renowned 12AY7 / 6072 vacuum tubes. With a gain of 35 dB at a standard 47 kOhm input impedance, it seamlessly accommodates both high-output moving magnet/moving coil (MM/MC) cartridges, as well as low-output MCs via an external step-up transformer.
Every single component contributes to the unique sonic identity of the audio signal. For this reason, we completely bypass mass-produced components in favor of proprietary, in-house manufactured parts and advanced materials. We utilize pure silver with point-to-point hand wiring to deliver a transparent, expansive soundstage that captures the emotional essence of recorded music.
Our commitment to absolute quality dictates that we manufacture all sound-critical components entirely in-house. To ensure uncompromised, lifelike sound reproduction, every device is meticulously fine-tuned and voiced in collaboration with the musicians involved in the original recordings.
