Pathos Logos MkII

The Pathos Logos MKII is a hybrid integrated amplifier delivering 110W per channel into 8 Ω and 220W into 4 Ω, featuring ECC88 preamp tubes and a heavily biased Class A/B Mosfet output stage.

Behind the signature original design, the new Logos MKII introduces a series of innovative solutions, some aimed at further enhancing the amplifier’s sound quality and others to meet the demand for versatility and functionality in a high-end device.

Purely resistive analog volume control with digital management and constant input and output impedance, adjustable display, and all functions remotely controlled. The fully balanced signal allows you to take full advantage of a symmetrical source such as the Pathos Digit and Pathos Endorphin.
