Features
This independent D/A converter explores new musical frontiers in a manner only possible to Esoteric, the acknowledged leader in Super Audio CD/CD playback.
The
It has been specifically developed to reproduce the ambience and resonance that is found on Super Audio CDs.
DAC “AD1955” with DSD input
The DAC device features “AD1955” supporting DSD and PCM signal input in a differential configuration.
It can fully express the presence and smooth frequency response that the Super Audio CD format delivers and can elicit superior performance also from regular CDs.
The
•Right and left analog power transformers, analog power supplies and analog audio circuits are completely independent while using the exact same components and the same layout pattern.
•The analog output units employ discrete circuits with high- voltage power.
•The power transformers comprise a total of three high- efficiency audio R core transformers: one digital and two analog transformers.
The analog power supply uses discrete power stability circuits.
•A digital filter OFF function is provided.
Straight signal transmission
A straightforward PCB layout of both the digital and analog circuitry prevents loss of tonal clarity.
A
The usual analog filter in the Fs/2 region has been dispensed with and there are no switching or adjusting circuits. Filtering elements and transmission circuits in the power supply and elsewhere have been optimized.
Versatile interface that handles a variety of input formats
In addition to S/PDIF, AES, i.LINK and other formats, the
•All input terminals can handle 192
•DSD signals from Super Audio CD are input either via ES- LINK, a proprietary Esoteric format, or i.LINK.
•Two XLR terminals handle Dual AES and
•CH_SEL selects audio channel when
Word sync for synchronizing with external equipment
The Word sync feature provides an OUT mode for outputting a word clock and an IN mode for allowing the unit to lock to an external clock.
The large and highly accurate VCXO crystal oscillator has been specially designed for the
conversion as well as the highly accurate synchronization for the transport unit.
Further, the Word sync input is optimized to input the ultra- precise

Highly rigid chassis completely eliminates internal and external vibrations preventing sound and quality deterioration
Thick aluminum is used in the top, side and front panels as well as in the corner sections while a solid 5 mm thick steel plate with quenched steel pinpoint legs (patent pending) support the entire structure. For greater strength, the internal chassis has a compartmentalized design that adds rigidity, suppresses vibration and effectively removes all electrical interference. The top panel features an 8 mm thick aluminum plate to obliterate any concern for the impact of speaker sound pressure that normally affects conventional designs.
The solid aluminum front and side panels with their brushed finish, the top panel with its beautifully crafted logo and the curved corner design that increases rigidity and reduces vibration all contribute to the sense of quality found only in 2- channel D/A converters designed for the ultimate Super Audio CD/CD system.
The output jacks are not mounted on the PCBs but on the rear panel to protect analog PCBs and the jacks from physical stress and complex vibration modes. Securing the analog PCBs to the internal chassis and the output jacks to the rear panel prevents impairment of sound quality from a failure in the mechanism.
