New Pathos Acoustics Kratos amplifier

New Pathos Acoustics Kratos is now in production. Kratos' name comes directly from its most important feature: power. In Greek mythology, indeed, Kratos was the god of strength, might and power. Kratos is based on Pathos’ hybrid circuit, with tubes pre-stage and Mosfet final stage; it has 200W for each channel. But that’s not all. Kratos’ pre-stage and final stage are clearly separated, with a prestigious pre-out and direct input to final stage; both pre-out and final stages are balanced XLR .

Its preamplification circuit is in pure class A; it uses Tung-Sol ECC803s tubes: sound is warm, deep, dynamic. Final Mosfet stage in class AB is strongly polarized in class A; its great power both at 8 and 4 Ohms makes Kratos able to drive any loudspeaker.

Kratos is also headphone amplifier with a dedicated circuitry (2 W @ 32 Ω).

Design is inspired by Logos, the great Pathos’ historic product. But this is a simple aesthetic affinity: similarities stops here. Kratos hides new technical solutions which make it the leading-edge-product between non-InPol amplifiers.

Kratos’ basic features (5 RCA, 2 balanced XLR, digital display, remote-controlled functions) could be improved by a DAC (optional) and a RIAA phono input (optional).
