ESOTERIC Grandioso P1 (SILVER)
Reference Digital Source
VRDS-NEO "VMK-3.5-20S"VMK-3.5-20S ESOTERIC is justifiably proud of this VRDS-NEO transport mechanism. Remarkable improvements in readout accuracy have been achieved by utilizing a high-precision turntable and correcting the disc surface shake occurring during disc rotation. The P1 features the VMK-3.5-20S VRDS-NEO with a refined drive circuit design. A pair of selected ball bearings is used in the spindle shaft bearing assembly, and there is a micron-level accuracy duralumin turntable with a 20 mm-thick steel turntable bridge for a total mass of 5.2 kg. In addition, the highly trusted mechanism of the P1 has been further refined with a high-magnetic-flux-density magnet-driven coreless three-phase brushless spindle motor, thread feed control (which evolved from the concept of the premier P-0 series), and a sliding-shaft-structure pickup that ensures that the laser beam is always at a right angle to the disc. VS-DD* spindle servo driver
The P1 uses the VS-DD dedicated spindle servo driver to drive the spindle motor that functions as the core unit of the VRDS-NEO mechanism. Using a three-channel discrete amplifier circuit to optimize the current waveform supplied to the motors, the VS-DD suppresses vibrations, enabling smooth spindle drive operation and highly precise servo control. The dedicated toroidal power supply unit is mounted in a separate power supply unit housing, enhancing noise isolation effects.

Two-chassis structure for main unit and power supply unit
Following the concept employed in our trademark P-0 series, a two-chassis structure is used in the traditional ESOTERIC flagship model. The power supply unit has been expanded to full-size, making it possible to include even more extravagant power supply circuits. A total of four independent toroidal power transformers are installed to supply clean and stable DC power to each circuit (VS-DD circuit, drive mechanism drive circuit, digital output circuit, and clock circuit).
Extensive material utilized both internally and externally
The inside of the main unit chassis has a double-deck structure and 3D optimized chassis construction connecting each circuit block with the shortest signal paths. Thick aluminum materials are used for the exterior, and the 5 mm-thick steel bottom chassis is supported at four points on original ESOTERIC pinpoint feet. Vibration is effectively controlled and thorough measures have been taken for rigidity.
Various digital output terminals
The P1 is equipped with five types and seven channels of digital output terminals (ES-LINK x 2, XLR x 2, coaxial x 1, i.LINK 4p/6p x 1 each), including a new dedicated ES-LINK4 terminal and dual XLR terminals supporting past.versions of ES-LINK.
Luxurious leather-finish remote control
Made of aluminum with just the right heft, the remote control has a leather finish that is supple and comfortable in your hand.
