TT Pathos

The first appearance of Pathos on the hi-fi scene did not go unnoticed: a short time after its debut, the T.T. has achieved a solid position among those very few components which contribute to writing the history of High-Fidelity.

International audio reviews welcomed the first product from Pathos with front page covers, highly enthusiastic comments and numerous prestigious awards.

When listening to music reproduced through a T.T. amplifier, everyone can experience the honest difference in terms of musicality, transparency, tonal colour and absence of listening fatigue.

The reason why this difference can he consistently and immediately appreciated is because the T.T. is different.

This difference is named InPoL®, the exclusive worldwide patented pure Class A feedback-free circuitry which has been claimed to represent the most important innovation in musical amplification of the last years.

Amplificatore a valvole

InPoL (Inseguitore Pompa Lineare – Linear Pump Follower) is a system patented by Pathos Acoustics which has enjoyed great success and won many awards.

Inpol devices have a special sonic personality obtainable only by means of this particular circuit design – fully balanced in Class A using a single solid state component in follower configuration, with high current gain and with voltage gain together. The valve amplifier amplifies the input signal voltage and InPol supplies the current to drive the loudspeakers without any further amplification. 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 of between 25% and 50% together with a low output impedance which is fundamental for the damping factor, and further improved by the double InPoL.

Highly selected components, pure silver Pathos signal wiring, and craftsmanship of the highest level are the most appropriate compliments to T.T. reference sound.

Through the years, TT has been constantly perfected and updated in order to keep this living legend alive.

Today TT is available in its original volume configuration – a purely resistive 24-step manual volume control – and also in a remote controlled version – an optical device which drives a battery of read relays (vacuum packed, thorium contacts), which drive a network of precision resistors (1% metal layer) in 1dB steps.?Be it in the Americas or the Old World, T.T. has achieved a level of respect across the globe that one can only describe as unanimous, whether in terms of originality of industrial design, uniqueness in circuit topology, or ultimately, sincerity in sonic reproduction.

Simply put: T.T. exists for those who believe that music is food for the soul.
