RIAA Equaliser Stereo Preamplifier

Clarinet's PHONO is a sophisticated three-stage active RIAA equalizer circuit featuring the renowned 12AY7/6072 tube. With a gain of 35dB at a standard input impedance of 47kOhm, it seamlessly accommodates both high-output level MC cartridges and low-level output MCs when paired with a step-up transformer.

Every component contributes to the unique sonic identity of audio signals. That's why we meticulously select only the finest materials only that work together in perfect harmony. We use special silver (Ag) wire to deliver a clear and rich sound that captures the emotional essence of recorded music. Our commitment to quality means that many components are handcrafted, ensuring lifelike sound reproduction through rigorous testing with the musicians involved in the recordings. 

Key Features

Fully hardwired structure utilize premium silver wire for both signal and PSU sections
In-house constructed silver lead-out wired resistors
Highest-grade silver capacitors
Highest-grade pure silver input / output connectors
