About the Grandioso S1X
The Esoteric Grandioso S1X is a flagship Class-A stereo power amplifier that represents a new milestone in high-end audio, succeeding the Grandioso S1. It inherits the dynamic design of the M1X monoblock with a newly designed 5-parallel push-pull drive stage using large bipolar transistors, providing full musical expression with precision and dynamism. Featuring superior power linearity (50W/8Ω to 100W/4Ω), it offers transparent and detailed Class-A sound in a compact half-space form factor compared to monoblocks. Key highlights include ES-Link Analog transmission for ultimate fidelity, three independent toroidal-core power transformers, channel-independent high-capacitance capacitors (10,000μF × 6/ch), pure copper busbars, balanced audio circuits, and support for stereo or bi-amp modes. The chassis optimizes vibration control with rigidity-flexibility balance, dual honeycomb grilles, semi-floating top panel, pinpoint feet, and wave-shaped heat sinks. It supports ES-Link Analog, XLR, and RCA inputs, with DC trigger for integration.
