Fully discrete Diamond Difference design , without any OPA and couple caps in the signal channels.
High working voltage (+/-35VDC) class A design .
Uses 3 units R-core transformer .
Total of 20 groups dedicated power circuits ( 11 groups of high-quality class A parallel connection PSU with dedicated DC supply double-stage PSU power supply for digital parts , 8 groups discrete dedicated linear double-stage PSU power supply for analog parts ) and more than 35,000uF caps are used to purify the power supply.
Uses most Hi-end grade parts and exact match transistors.
6 groups digital input : BNC coaxial / AES / RCA coaxial / Optical / USB / I2S
output : RCA *3
USB Audio Class 2 High-speed Input from Windows / MAC / Linux
Supports High / full speed Asynchronous Transfer Mode up to 384K / 32Bit ability .
Resolutions support 16 / 24 / 32 Bit with sampling rate support 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz ( USB )
Supports up to 24 Bit/192KHz ( SPDIF )
The DSP digital processor can supports NOS, 2X, 4X and 8X oversampling customers setting.
Sound characteristic : Musical (coloration ) but detail , smooth but not too warm .
What's new in the SA-2 ( Upgrade from Reference 9 ) :
The full new design DSP processor solder on the main board direct for best signal transfer and faster process data and clock , it have better jitter refuse performance .
It support up to 32bit / 192KHz through USB and I2S input, 24bit / 192KHz through SPDIF inputs ( NOS, 2X , 4X and 8X oversampling support . ).
It is a full new design concept . The SPDIF inputs have applied specialty interface process the data, this is allow the best parameter design for different type SPDIF inputs.
IN1 : BNC input ,up to 24bit / 96KHz support .
IN2: AES input, up to 24bit / 192KHz support .
