Esoteric S-05 Stereo Power Amplifier

Witness the birth of an all-new stereo power amplifier, borrowing from the engineering techniques utilised in Esoteric's flagship Grandioso M1X mono block amplifiers.

The new S-05 – a class-A power amplifier thoroughly focused on delivering all of music’s unique tonal qualities from a more compact stereo configuration, embracing the philosophy of the Grandioso M1X: “minimal circuitry – maximum output”.

This can be run as a stereo power amplifier, or you can run it bridged as a monoblock amplifier and achieve double the power (with two S-05 units); ie 120w into 4ohms of Pure Class A solid state power!
