PSI Audio is a brand that swims against the current. While everyone else is obsessed with DSP processors, the Swiss engineers from Yverdon-les-Bains say a firm "no." For over 40 years, they have been building 100% analog monitors, based on the premise that since ears and sound are analog, the monitoring chain should be too. Every speaker is hand-assembled, soldered, and measured in an anechoic chamber in Switzerland, with a precision worthy of the finest watchmakers.

The secret to their unique sound lies in patented analog technologies like AOI (Adaptive Output Impedance) and CPR (Compensated Phase Response). The former ensures the speaker cone is constantly monitored and corrected, delivering unprecedented speed and transient clarity. The latter is a complex filter network that perfectly phase-aligns the signal without digital processing, resulting in impeccable stereo imaging and depth. All of this is driven by proprietary Class G/H amplifiers, which combine sonic purity with massive headroom.

At Wired Tunes, we offer PSI Audio—from the compact A14-M to the powerful 3-way A25-M—to purists who don't trust digital corrections. This is gear for those who want to hear the naked truth about their recording, not the result of a processor's calculations. If you are looking for a monitor that acts as a transparent window into your sound, behaving like "wire with gain," PSI Audio is the end of your search.
