Phædrus Audio PHLUX active phono cartridge moving-magnet motor system 

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.

      Er, quite the opposite actually Dave! 🙂 May depend on the cart/deck you heard, how it was set-up, etc. There are some excellent models out there. The Ortofon 2M Black is superb, for example.

    run the Phlux II on an Onkyo CP-1055FII with a T+A Pulsar P1000 preamp. Nothing too fancy, but neither bad at all. The sound is the best I’ve heard from any other system below 3500 bucks.
    Timing, stability, integration, foundation, stage, blackness.
    Highly recommended. Support by the manufacturer is superb, too.
