The PSM156 builds upon the performance of the PSM136. It has 6 fully independent star wired 15 Amp output sockets but operates with 52 independently tuned filter elements, as opposed to the 39 used in the PSM136, which further reduces Normal and Common mode Electromagnetic interference. It is internally wired using Silver plated Oxygen Free Copper wiring with PTFE insulation and offers a massive 30,000 amps surge protection. The PSM156 also offers additional circuitry to re-balance the AC sine wave, removing all DC components enabling transformers to work more efficiently and quietly, further reducing the noise floor and improving definition.


A greatly reduced noise floor due to the purification of the AC power supply, the removal of all Direct Current components plus a star earthing format and earth management system, which eliminates ground loop hum, further reducing the noise floor and greatly improving your Hifi systems performance. Individual instruments within the stereo mix gain an increased sense of separation, depth, definition and clarity, making it far easier for the listener to determine the positioning of the individual instruments within the Stereo, Left - Centre - Right sound stage, resulting in a far more engaging and musical experience.
