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
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.
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.
