Esoteric SA-50 CD/SACD Player and DAC -Super Audio CD, CD (CD-R/CD-RW compatible) The unit is in mint condition like new.
The SA-50 has a highly advanced pre-D/A stage digital to digital signal conversion capability fully utilizing the 32 bit digital processor on board.
CD/SACD player and DAC Disc formats: CD, SACD, CD-R/CD-RW Analog outputs: Unbalanced on RCA jacks, balanced on XLR jacks Digital inputs: USB (“B” type connector), coaxial, TosLink Digital outputs: Coaxial, TosLink Word clock input: TTL levels, 75 ohm, BNC jack (can lock to 44.1kHz, 48kHz, 88.2kHz, 176.4kHz, 100kHz) Dimensions: 17 3/8” x 6” x 13 7/8” Weight: 39.6 lbs.
Highly advanced digital conversion capability
PCM up-convert function is available for PCM signals read from Redbook CDs, and PCM up-conversion capability is allowed from other external digital devices. Oversampling frequency is selectable from original Fs, ×2 (64 / 88.2 / 96 kHz) or Fs, ×4 (128 / 176.4 / 192 kHz). The SA-50 can also convert PCM signal to DSD signal. As for Super Audio CD, not only processing native DSD signals directly into analog signals, the SA-50 can also convert the DSD signal into a PCM signal, with oversampling frequency selectable from ×2 (88.2 kHz) or ×4 (176.4 kHz).
These functions provide a wide range of options to match to your hi-fi system, or your general listening preferences based on your choice of software.
USB and digital inputs
The SA-50 is a CD/SACD player and is also highly capable as a standalone 32 bit D/A converter providing 3 digital inputs. (COAX, OPTICAL, USB). PC connectivity via the USB interface will provide audiophile playback quality to your hard drive based streaming audio media.
Dual PLL circuits reduce jitter when connected to external digital source devices
The SA-50 shares dual stage PLL jitter reduction with the ESOTERIC D-05 D/A converter, and is highly capable as a standalone D/A converter / re-clocker, when connected with CD transports, media servers, or other external digital devices. The second stage PLL circuit has its own voltage controlled crystal clock, and re-clocks the signal produced by the first stage PLL circuit. Dual PLL circuits, with two different characteristic responses in jitter reduction effectively purify the input digital signal.
32 bit digital volume attenuator
The SA-50 features a 32 bit digital volume attenuator. Wide 32-bit headroom ensures highly precise volume attenuation for disc or digitally input data playback without degrading the signal.
As a result, the SA-50 can be used as a digital preamplifier, connecting directly to a power amplifier.
High quality 2 channel dedicated analog audio output Precise imaging and deeper sound stage
The analog audio output circuits are in a dual mono configuration producing excellent channel separation. 2 channel dedicated circuit design further enhances precise imaging, transparency, separation and depth of soundstage.
RCA (single-ended), output or XLR (fully-balanced), output is selectable. The analog signal path that is not used can be completely de-activated. XLR terminal pin assignment is user selectable between 2 pin hot or 3 pin hot*.
*The hot pin is fixed to 2 pin hot for dual (RCA + XLR), output mode.
Rich and high speed power supply capability
The large custom designed toroidal transformer, has a very highly efficient power supply capability. This provides electrical power to the drive mechanism and audio circuits very quickly, without adding noise or distortion to the signal path.
The SA-50 features a WORD SYNC input terminal to accept an incoming external WORD clock signal* from an optional external master clock. The incoming ultra-stable clock signal produced by an external master clock sync generator (ESOTERIC G-03X or G-0Rb), effectively upgrade the unit; delivering higher performance with better acoustic transparency, greater separation and a wider sound stage.
*The SA-50 will not accept an external clock input signal when used only in its DAC operating mode.
Highly rigid chassis construction for optimal resonance control capability
The extra thick aluminum front panel and T5mm aluminum top and side panels help the unit to control unwanted vibrations and resonance. The bottom chassis features a heavy duty 5mm thick steel plate combined with three pinpoint isolation feet made of quenched steel. This base design helps to provide a level platform that is vibration free. Highest order resonance-control functionality is accomplished through this engineering in a contemporary audiophile design.
