Puritan Audio Labs PB104-DC Mains Purifier



Although representing the entry level to the Puritan Sound with its wider, deeper soundstage, greater detail, greater realism, greater enjoyment, there has been no compromise with the design and specification of the Power Brick Range.

A Revolutionary Way to Raise the Performance of Your System for Very Little Money

These units encompass the ethos and design elements and expertise that make Puritan products so uniquely special. Embodied in a stainless steel magnetically shielding body, they have 4 x 15 Amps outputs, 20 discrete filter elements that progressively but comprehensively protect against both common and differential mode interference, add cleansed star earthing, DC offset correction (-DC Model), massive three dimensional non-sacrificial surge protection and we present a fabulous introduction to The Puritan Sound for the budget conscious audiophile.

If you just wish to have DC Offset correction without any filtration the PBDC-Symmetry model will do just this in addition to providing 4 Star wired outputs that ensure connected components each receive equal power.

  • Multiple cumulative, sympathetically tuned stages of purification ( 20 independent elements), comprehensively remove both common and differential modes of interference
  • Rebalances the AC sine wave, removing all DC components, this enables transformers to work silently at their very maximum efficiency realising their full dynamics and power range
  • Four 15 amp outlets each with independent re-filter stages for differential mode disturbances helps to avoid cross contamination between connected equipment.
  • Equal resistance, maximum power routing to all outputs realises full dynamic performance
  • Massive 9,000 amps repetitive rating of three dimensional non-sacrificial surge protection guards your valuable equipment against lightning damage etc.
  • Star earthing plan avoids hum loops, reduces the noise floor, for greater silence and definition
  • Cleansed earth removes noise from the earth line further enhancing clarity and dynamics
  • Internal wiring silver plated OFC copper PTFE insulation
  • Electrically and magnetically shielded casing
  • Rated Voltage 110-250Vac 50/60Hz
  • IEC type C14 Input
  • Dimensions in mm W 250 D130 H 90 mm
  • 5 Years Guarantee

Why Purify?

Washing machines, fridges, computers, plug in power supplies, low energy lighting, dimmer switches, heating pumps, thermostats, solar power installations, the list of culprits directly injecting rubbish into our mains supply is endless. Effectively anything connected to the mains in your house and all of your neighbours houses contributes to the problem. And that is before you consider more distant heavy industrial machinery, and it doesn’t stop there….. In the air there’s mobile phone, radio and TV transmissions, WiFi, Bluetooth, emergency services transmissions (the list is never ending) all totally saturating the atmosphere. Your household wiring and equipment cables acting as antennas, absorb and pile these very significant disturbances on top of the considerable interference already in them.

The flood of fizz, hash, spikes, snap crackle and pop delivering itself into your sensitive dacs, preamps, amplifiers and video displays swamp and confuse everything they are trying to do…… and it gets worse! The DC voltages, normally present in your mains supply, smother and suffocate the transformers in your equipment. Transformers need to “breath” freely and fully, in and out, following the AC mains frequency. The presence of DC leaves them noisily gasping for breath and unable to deliver their full power and punch.

When this occurs, the clarity, dynamics and emotion of the performance that you are trying to recreate is smothered under a barrage of interference pollution and waveform distortion. Your audio and visual equipment groans, buzzes and rattles, …. sound is constricted, muddled, harsh, two dimensional and unrealistic.

With the ‘Puritan Treatment’ dynamics and definition take an almost unbelievable stride forward, individual instruments gain air between them, their sound and timbre become convincing of the real thing, the sound-stage moves out of your speakers and into the room with gains in three dimensionality and with clarity definition and space between the instruments for them to inter-relate rather than muddle each other. Your listening will become a far more engaging and pleasurable experience.

Problems with mains and airborne disturbances also greatly compromise visual display performance causing definition to be dulled and the dynamics squashed. With the ‘Puritan Treatment’ the visual experience elevates to a higher level of noise free richness, blacker blacks, greater clarity, increased vibrancy and realism.

The Puritan Way

Our aim throughout is to produce the ultimate mains purifier solutions and to present these to the consumer with a level of meticulous build quality that means that an investment in a Puritan product is an investment that will be enjoyed for decades to come.

Look inside any of our products and you will see they are crammed with engineering.

We use multiple filter elements, 39 in the PSM136, each carefully and precisely tuned to inter-relate with each other to produce an increasing, cumulative cleansing effect with the lowest impedance high current paths to preserve maximum surge demand and dynamic agility.

By maintaining the power of equal resistance paths to each outlet and with every single type of mains degradation mode comprehensively dealt with, right down to the provision of a precision cleansed, star reference grounding structure, all Puritan design aspects come together to enable your system to perform to its absolute peak ability.

Mains purifiers require a means of connecting from the wall to the purifier and from the purifier to your equipment. To preserve the ultimate quality of mains supply we have developed our unique ‘Proprietary Dissipative Technology Mains Cables’. These employ a very substantial 25 amp rating, extremely high purity plated copper conductors enclosed in a superior dielectric silicone insulation which in turn is encased with a mechanically damping silicone sheath to provide a vibrationally “dead” super silent conduit. We then massively enhance this already terrific cable with a very special technology:

With normal (unshielded) mains cables, airborne interferences enter the conductors directly, polluting your equipment power paths, disrupting signal processing and delivery. With ordinary shielded cables airborne interferences are gathered and dumped into your system’s earth and through this route disrupt your processing and signal paths – a lose – lose situation! We solved this dilemma by developing our unique Proprietary Dissipative Technology shielding system. With our unique dissipative shielding the interferences bombarding the cables are absorbed into the dissipative shield, burned up and dissipated as heat – avoiding interference either reaching the conductors or polluting the system earth.

A thoroughly thought through and researched, highly advanced mains cable solution.

Other Puritan products to improve audio and visual experience by the elimination of mains disturbance problems include plug in silencers to place in sockets around the house to prevent re-radiation of disturbances, quietening the overall EMI/RFI smog and high specification speaker cables protected with our dissipative technology to prevent radiated disturbances attacking signal integrity at the last stage.
