Puritan Audio Labs PSM156 Mains Purifier

The Puritan Audio Labs PSM156 builds upon the brilliance of the legendary PSM136 retaining the precision symmetrically balanced circuitry and 6 fully independent outputs. Increasing the number of independently tuned filter elements from 39 to 52 enables your system to deliver even greater delicacy and detail whilst enhancing dynamics and punch.

The PSM156 will lift your system into a new dimension. Definition takes an enormous stride forward, individual instruments gain air between them with their sound and timbre becoming believable, the sound-stage will move out of your speakers and into the room with gains in three dimensionality with clarity definition and space between the instruments for them to interrelate rather than muddle each other. Your listening will become a far more engaging and pleasurable experience.

DC Blocking

Have you ever experienced a mechanical hum from the transformer in your amplifier or power supply? Sometimes the hum is caused by a bad transformer. Most of the time it is caused by DC current contaminating the AC supply. This problem is becoming more and more common, in large part due to the widespread adoption of LED lighting. The toroidal transformers used in hi-fi components are particularly susceptible to this problem. Puritan Audio Lab’s DC blocking technology completely eliminates this hum by removing the DC contamination.

Optional Facedown Converter Plate

The Puritan Audio Labs PSM156 comes as standard with four rubber feet for horizontal placement. The optional facedown converter plate allows the PSM156 to be mounted vertically, with the sockets facing upwards. The converter plate replaces the standard front fascia with outriggers and isolation feet. It is a great option if you would like to place your PSM156 behind your hi-fi rack or other furniture.

It is available as a no-cost option on all new Puritan PSM136, PSM156 and PSM1512 mains purifiers.

What our customers say

“I wasn’t expecting a night-and-day difference, but that’s exactly what I got. The PSM156 completely eliminated the transformer hum. Now all I can hear is music.”
Michael, London

“I’ve tried a few conditioners over the years, but the PSM156 is the first one that didn’t blunt the dynamics. The sound is cleaner, more composed and somehow more natural. It just makes everything easier to listen to.”
Jonathan, Leeds
