We opted for a return to a linear power supply (transformer – bridge – capacitors). Leaving the power of 45W on 8Ω unchanged, we wanted to give more power on 4Ω: we, therefore, increased the BIAS current, which made larger radiators necessary than in the previous version. The different choice of power supply allowed us to redesign it in a dual-mono configuration: 2 transformers (one per channel), 2 rectifier bridges (1 per channel), and 4 capacitors (2 per channel).
InPoL devices have a special sonic personality obtainable only through this particular circuit design – fully balanced in Class A. In this way, the signal is entrusted to the valves and becomes a true copy of the original, with all the quality, purity and harmonic content of the original. This technology allows an increase in the theoretical output in pure Class A from 25% up to 50% together with a low output impedance which is fundamental for the damping factor, and further ...

Our take on the brand
Look inside the brand
Our interview with the brand
What are two key technological innovations or strong opinions that differ you from other brands?
Pathos stands out for two fundamental elements that represent our identity: technological innovation and design philosophy.
The first is INPOL, our exclusive patented technology: a hybrid circuit that combines the warmth and musicality of tubes with the strength and precision of MOSFETs. The tubes shape the sound in terms of amplitude, offering transparency and naturalness, while the MOSFETs provide the current needed to drive the speakers, working in pure Class A, without distortion or feedback. The result is a dynamic, detailed sound that is incredibly faithful to the original. With the evolution of DOUBLE INPOL, this philosophy reaches higher power and even more refined performance, while maintaining the sonic character that defines us.
The second is our choice to remain true to the essence of sound and the true meaning of “Made in Italy.” Every one of our products is designed and built in-house at our facility in Vicenza: from the electronics to the processing of aluminum and wood, to the painting, every phase is closely overseen by our team with artisanal care and obsessive attention to detail. We don’t just build amplifiers: we create unique objects, designed for those who seek an authentic, thrilling listening experience, without compromise, where beauty, technique, and passion coexist in perfect balance.
What's your approach to customer support?
In general, the ideal procedure is for the end user to contact their retailer or local distributor, who are always the first points of reference. However, it often happens that customers reach out to us directly: depending on the situation, I either direct them to our partner or assist them personally.
What truly matters to us is that the customer feels listened to and taken care of. That’s why, even remotely, I often personally handle support cases: not due to a lack of trust in our distributors – with whom we have excellent relationships – but to show that every customer is important to us. We know that our amplifiers have a value that goes beyond the cost: they represent a passion, a conscious choice, often a dream come true. And those who own them have every right to feel in good hands.
