The new SA-50 is a:
- Stand alone 32 bit dual mono D/A converter up to 88.2, 192 and even to DSD
from S/PDIF, USB (Including PCM from a laptop) and optical inputs.
- Digital pre-amp with attenuator (can feed directly into a power
amp).
32 bit CD/SACD player with PCM to DSD and DSD to PCM
functionality.
- A re-clocker with second PLL for external digital devices. (Plus master
clock generator input for external clock).
VOSP Mechanism:
VOSP (Vertically-aligned Optical Stability Platform), features a specially
designed shaft-mounted laser pickup assembly. This pickup system evolved from
Esoteric's P-01 and P-03 transports. This pickup design ensures that the laser
optical axis is always at the center of the data track for optimal reading
capability. With VOSP implementation, no off axis error correction is needed
because no off axis data tracking is allowed.
High mass / resonance-free mechanism stabilizer:
The VOSP mechanism is rigidly clamped by a steel plate and a large diameter
stabilizer made of 8 mm-thick steel to reduce unwanted resonance caused by high
speed disc rotation. The entire mechanism assembly is directly mounted to the
bottom chassis and two interior steel brackets rigidly hold the mechanism for
superior anti-resonance properties.
Full 32 bit processing D/A converter devices:
The SA-50 features the latest 32 bit processing "AK4392" advanced multi-bit
DAC device produced by Asahi Kasei EMD. The AK4392 has a highly precise D/A
conversion capability with extended 32 bit processing throughout all output
stages. The 32 bit processor also has enough room for 24 bit or lower data flow,
and greatly contributes to a "three-dimensional" audio imaging experience. The
SA-50 uses 1 chip per channel, in a dual mono configuration gaining maximum
performance out of the 32 bit AK4392. With this implementation, high purity
digital signals are converted to well defined, high-density analog signals.
Highly advanced digital conversion capability:
DSD to 32 bit PCM conversion for SA-CD and PCM to DSD conversion for Redbook
CD. The SA-50 features user selectable digital signal conversion capability. The
highly advanced digital conversion functions of the SA-50 include 32 bit PCM
processing to provide a wide range of options to match to your audio system, or,
your general listening preferences based on your choice of software. (1) The
SA-50 can directly process native DSD signals into analog signals, and, can also
convert the DSD signal into a 32 bit PCM signal. Over sampling frequency is
selectable from x2 (88.2 kHz) or x4 (176.4 kHz). (2) PCM to DSD conversion
capability for Redbook CD sources and for PCM signals input from external
digital devices. (3) PCM signals are processed with a high quality 32 bit
digital filter to enhance natural reproduction capability. Over sampling
frequency is selectable from x2 (88.2 kHz) or x4 (176.4 kHz). (4) 2 modes are
selectable for PCM digital filter. (FIR mode / Short delay mode).
High quality 2 channel dedicated analog audio output for precise
imaging and deeper sound stage:
The analog audio output circuits are also in a dual mono configuration
producing exceptionally good channel separation. RCA (single-ended), output or
XLR (fully-balanced), output is selectable. During playback of the selected
output mode, the analog signal path that is not used is completely de-activated.
This 2 channel dedicated circuit design further enhances precise imaging,
transparency, separation and a deeper sound stage.
High speed power supply capability:
The large custom designed toroidal core transformer, has a 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.
Word synchronization:
The SA-50 features a WORD SYNC input terminal to accept an incoming external
WORD clock signal. The input can operate with 44.1 / 88.2 / 176.4 / 100 kHz
clock signals. The unit can also operate using an ESOTERIC original 100 kHz
Universal Clock signal (Single freq. compatible w/ SACD/CD and DVD). The
incoming ultra-stable clock signal produced by external components such as a
master clock sync generator (ESOTERIC G-03X or G-0Rb), effectively upgrade the
unit, delivering higher performance with better acoustic transparency, improved
channel separation and a more detailed and wider sound stage.
Dual PLL circuits reduce jitter when connected to a digital source
device with no WORD SYNC function:
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, even when the unit is connected to
a transport with no WORD SYNC function. You can set this second stage PLL to off
when the unit is connected to a transport which has a WORD SYNC input function.
Highly rigid chassis construction:
The SA-50 front panel is made of thick extruded aluminum. This helps to
insure chassis rigidity, reducing unwanted vibrations and resonance, while also
providing a stronger support structure for the center mounted VOSP mechanism.
The top and side panels are made of 5 mm thick aluminum. The bottom chassis
features a heavy duty 5 mm thick steel plate. The toroidal transformer support
base also features a 5 mm steel plate for added resonance absorption. Combined
with three pinpoint isolation feet made of quenched steel, this chassis design
helps to isolate the unit from external vibrations, allowing highly stable and
precise VOSP mechanism mounting, and highly-rigid, resonance-free system
construction
