Phædrus Audio PHLUX active phono cartridge moving-magnet motor system 

17th June 2017

Buffered by a miniature impedance-converter, the company exclaims that this system, “…[offers] the performance of a moving-coil cartridge with the superior tracking and general convenience of the moving-magnet type.” A bold claim indeed

The miniature impedance-converter, which buffers the moving-magnet motor, is powered via the signal wires, in much the same way a capacitor microphone is supplied with phantom power. Hence, PHLUX-II may be fitted to any turntable and arm combination without modifications to the wiring.

The Phædrus Audio PHLUX-II active phono cartridge was developed for Pspatial Audio’s Stereo Lab needle-drop capture and equalisation software.


The PHLUX-II is particularly suitable for enthusiasts of historic recordings because. In addition to the standard hyper-elliptical stylus, a Shibata stylus and a stylus for 78 RPM records are available.

You can buy the PHLUX-II with or without an accompanying base-station directly from Phædrus Audio. The first commercial phono preamplifier to support the Phædrus PHLUX-II is the Groove Sleuth MINI, a non-equalising preamplifier. from Pspatial Audio.

It provides iLoop (a very low-noise loop-through) and it may thereby be used as a base-station for the PHLUX-II, with the iLoop signal moving to your existing phono preamplifier.

Whilst the Groove Sleuth Mini (£378) may be operated with the Pspatial Audio ‘resolve’ power-supply, it incorporates a rechargeable battery and a front panel switch which permits disconnection of the PSU.
