Purifi Audio is a quite young Danish start-up that got 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. Their desire is to remove all technical limitations in the enjoyment of reproduced music. Therefore, Purifi Audio dedicated their mission to focus their 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 analog 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.
The Purifi 1ET400A is a single-channel, ultra-high performance, analog-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.
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 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 fiber 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.
