Esoteric Grandioso C1X

Description

Construction without compromise

• 2 chassis dual monoblock design
• Semi-floating pre-amplifier module non-screwed with chassis for further unbound sense of the sound
• DC power supply design with dual AC inputs and dual DC outputs
• Total 5 power supply transformers, including four large-capacity Toroidal-core transformers and one R core transformer

All-new circuitry design that totally renovates the Grandioso C1

• Newly developed “Ultra Fidelity Attenuator System” that achieves prodigious resolution of 0.1dB/1,120 steps and smooth curve with Stepped Resistors Attenuator
• Unique integrated discrete amplifier module, the “IDM-01” exclusively designed for the C1X, for excellent sound quality by selecting parts and circuitry by ourselves in the same manner of discrete circuity
• Input selector with FET elements that eliminate affects from mechanical contacts and achieve excellent sound
• Unique current transmission format ES-LINK Analog supported on three inputs and two outputs*
• Excellent S/N performance by fully balanced circuit design
• The ESOTERIC-QVCS volume control that consists of four circuits on each channel for dual-mono and fully balanced design
• Ultra low noise logic control design
• The ESOTERIC-HCLD, an enforced current output buffer circuitry (2,000V/μs)
• Stabilized power supply circuit for buffer amplifiers (EDLC Suer Capacitor Array)
  _{* A matching power amplifier is under development. (as of July 2020)}

Other features

• Selector Knob and Volume Knob employing high-precision ball bearing for excellent operational feeling
• Input gain control: ±18dB (0.1dB step), L/R balance control: ±6dB (0.1dB step)
• Supports AV THRU setting that allows coexistence of AV amplifiers, in addition to conventional LINE inputs. (on all inputs)
• A high-grade double-faced aluminum remote control that controls ESOTERIC Super Audio CD players, network players, and DACs, as well as the Grandioso C1X. (RC-1334)
