  • Ultra-fidelity attenuator system with 0.1dB/1,120 steps
  • Discrete amplifier module "IDM-01
  • Unique ESOTERIC-QVCS volume control system that eliminates audio signal routing
  • ES-LINK Analog" proprietary current transmission system with 3 inputs and 2 outputs
  • ESOTERIC-HCLD output buffer circuit with 2,000V/μs slew rate current transmission enhancement
  • 2 XLR outputs and 2 ES-LINK Analog outputs enable construction of a multi-power amplifier system
  • 5-transformer configuration with 4 high-capacity audio toroidal transformers and 1 EI transformer for control system
  • Input switching circuit using FET elements eliminates coloration of sound quality by relays
  • High-precision ball bearing control knobs for smooth feeling without any blurring.
  • Input gain adjustment: ±18dB (0.1dB step), L/R balance adjustment: ±6dB (0.1dB step)
  • AV-through function with selectable input terminals
  • External control port RS-232C terminal
  • Power ON/OFF control by trigger input and power control of power amplifier by trigger output
  • Remote control with buttons on both sides to control ESOTERIC source devices (RC-1334)

 

Grandioso S1X
Intricate and dynamic. Open up and depict all of the music.

The Grandioso S1 "X" Edition, a new reference in Class A stereo power amplifiers.

Key Features
  • Newly designed drive stage with 5-parallel push-pull drive by high-capacity bipolar transistors
  • Class-A operation at 50W/8 ohms delivers a dense musical expression that combines precision and dynamism.
  • ES-LINK Analog transmission that challenges the limits of fidelity between pre/power
  • Excellent power linearity (50W/8Ω - 100W/4Ω) that produces overwhelming dynamics
  • Large-capacity toroidal-core power transformer that is highly adaptable to dynamic current supply changes
  • Three-transformer configuration with independent power transformers for the front stage, drive stage, and control system
  • High-capacity Grandioso custom block capacitors (10,000μF x 6/ch) for each channel
  • Pure copper busbars, ultra-thick wiring, and shortest pattern connections significantly reduce internal impedance.
  • Balanced audio connections for each circuit block to ensure low noise.
  • High quality sound parts such as FET switch for input switching and discrete amplifier module IDM-01 are used.
  • Two modes, BTL drive and bi-amp drive, are available for further system upgrades by combining two units.
  • Newly designed Class-A construction with an enlarged chassis the size of M1X
  • Chassis design optimizes internal vibration control by thoroughly pursuing a balance between rigidity and flexibility.
  • Dual honeycomb grills and semi-floating top panel for heat exhaust efficiency and a sense of sound emission
  • Specially constructed pinpoint isolation feet to reduce mechanical stress
  • Special wave-shaped heat sink to reduce peak resonance
  • Power ON/OFF control is possible via trigger input
