Mola Mola Phonostage Upgrade for Makua/Kula

Mola Mola Phonostage

AN ARCHIVAL GRADE PHONO STAGE

What was initially intended to be a simple RIAA add-on for the Makua Preamp has quickly spiraled into the quietest and 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 the MM stage, the two stages are fully independent, each realizing an equally short signal path. Input gain is switchable in 5dB steps over a 40dB range.

Input resistance and capacitance are individually switchable. Available EQ settings cover practically all known cutting curves, including most 78 RPM curves.

All settings are software-controlled, either on the fly via a smartphone or tablet using the Mola Mola Remote app or directly via the preset buttons. The preamp can be configured to route any input through the phono stage, allowing you to connect multiple turntables and cartridges.
