      19 PURIFI

      Purifi Audio is a quite young Danish start-up founded in 2019 by the three audio enthusiasts Bruno Putzeys, Lars Risbo, and Peter Lyngdorf. The Purifi headquarter is located in Roskilde, just 40 minutes drive from the core of Copenhagen. It desires to remove all technical limitations in the enjoyment of reproduced music. Therefore, Purifi Audio dedicated its mission to focus its R&D on loudspeaker drivers and power amplifier modules because Purifi Audio believes that those are the biggest limiter regarding sound quality. Purifi Audio represents the principle that you can’t solve a problem if you don’t deeply understand it. That’s why Purifi Audio is convinced that sound quality can be measured and claims they are fluent in analogue and digital next to all the domains of electromagnetics, acoustics, and mechanics. They approach the problems systematically and mathematical. Purifi takes care to upgrade the different distortion mechanisms independently, accordingly, ensuring that any deliberate improvement genuinely mirrors a genuine perceptible improvement regardless of what the signal is.


      PURIFI Amplifiers

      By now, PURIFI amplifiers have built up quite a reputation. PURIFI amplifiers are considered so good, that one no longer has to think about the settings to minimize distortion of any kind - because there aren't any. PURIFI amplifiers strive for perfection and do not suffer from harmonic distortion, intermodulation distortion or frequency-response aberration, regardless of frequency or load. 


      Purifi 1ET400A Amplifier Module

      The Purifi 1ET400A is a single-channel, ultra-high performance, analogue-input Class D amplifier module capable of over 400W of power and provides an audio quality level that sets the standard for power amplifiers of any operating class. This high-performance amplifier module is based on the Eigentakt technology from PURIFI. The 1ET400A is one of the most high-end options from our amplifier module category. Eigentakt is the implementation of PURIFI's continuing research into nonlinear control theory that produced the first mathematically exact largesignal model of self-oscillating amplifier controllers.


      Purifi EVAL1 Amplifier Stereo Set

      The Purifi EVAL1 stereo evaluation kit creates easy signal and power supply connections for a stereo 1ET400A setup. The kit is developed for evaluation purposes but is perfect suitably for DIY applications. The kit is supplied with two 1ET400A amplifier modules, one FE02 stereo front-end module and a power supply cable set. The FE02 front-end module allows you to easily connect a compatible power supply with the supplied cable set. The signal input is connected through XLR. Two pairs of banana-plug speaker connectors allow for easy speaker connections.


      Purifi Passive Radiators

      The Purifi PTT6.5PR is a 6.5” high-performance passive radiator, while the Purifi PTT4.0PR is a 4” high-performance passive radiator. They are both featuring Purifi's research-based technologies, including the Natural Surround and a cone made from a proprietary fibre mix.  Purifi developed a deep understanding of many performances degrading aspects for both amplifiers and transducers. Thanks to this understanding, the passive radiators from Purifi are the most high-end passive radiators available at SoundImports.
