What was originally intended to be a simple RIAA add-on for the Makua Preamp has quickly spiraled into the quietest and probably most versatile phono stage ever built. MC/MM input stages are optimized for current noise and voltage noise respectively. Unlike the more common arrangement of an MC head amp feeding into the MM stage, the two stages are fully independent, realizing an equally short signal path for both. Input gain is switchable in 5dB steps over a 40dB range.
