Purital Audio PSM156 Studio Master Mains Purifier (inc. 2 metre lead)

The 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.

PSM 156
26 March 2023  | 

Swapped from a non-filtering distribution strip; difference was immediately apparent. Blacker background, music has more depth front to back. Tracks have greater 3D; instruments appear 3 dimensional, rather than a collection of instruments pasted on to a 2D canvass.

Track components also seem more articulate than without the 156, and the space of the recording is more apparent; the ambience of the room is easier to discern - greater atmosphere/emotion.

The PSM 156 to my mind should be considered a component, as important as any other in a system, it is that good.

Great product, no hyperbole, it does what it is advertised as doing. Now for Puritan's Grounding products

Having read several reviews that were consistent in their very positive view of the Puritan, I decided to take the plunge and buy one. Any regrets? Absolutely not. This thing is quite simply superb in my system consisting of a WT Versalex, Leben CS600 and Harbeth P3s. It does what the maker claims and the reviews reflect. Very pleased.

Puritan Audio PSM156

Mains products are hit or miss but having several components with Toroidal Transformers I have been plagued but Transformer hum, watched a YouTube review of the PSM156 so took a chance, Igloo had a great deal and the unit arrived within a day or two. Plugged everything in and silence, no hum at all, then as I played some music I got improvement in detail, sound floor, cannot recommend enough

Excellent investment
21 April 2022  | 

I have found the Puritan 156 to be a great success. I am running a Lumin streamer to a pair of monobloc valve amps and active stereo subs. The Puritan removed all hums and buzzes from the power amps and I perceive a noticeable 'tightening' of the bass - and perhaps a better soundstage too. And it is great to be able to run the entire system through one mains socket and be confident enough to leave it permanently switched on. Highly recommended.
