Isoteric S-05 Stereo Power Amplifier

Witness the birth of an all-new stereo power amplifier,
borrowing from the engineering techniques
utilized in our flagship Grandioso M1X mono block.

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”.

Key Features
Lavish material employment, simple and straight circuit design concept borrowed from the Grandioso M1X
Finely detailed Class-A sound with super dynamics – an Esoteric’s signature tone
Dual monaural construction in all stages including current smoothing circuit for better channel separation
Esoteric’s proprietary current signal transmission, “ES-Link Analog” delivers music signal with exceptional high power and fidelity.
High capacity bi-polar 3 parallel push/pull circuit that instantaneously responds to the music signal
940VA large EI-core power transformer that responds to dynamic current supply changes with high speed
Large “Grandioso grade” custom capacitors on each channel (10,000μF × 4/ch)
Balanced input amplifier for stable, noise-free signal transmission
BTL / Bi-amp mode switch for dual amplifier configuration
DC Trigger for sequential power ON/OFF with the N-05XD
Esoteric’s unique isolation feet and semi-floating top panel
Unique shaped heat-sink to minimize its own peak resonance
