Main chipset: AD1955A, DIR9001, TE7022L, OP275G, JRC5532DD
 
D / A converter chip: AD1955
The AD1955 is a complete high-performance, single chip stereo digital audio playback system, the number of Σ-Δ modulator, digital interpolation filter and continuous-time differential current output DAC components. This audio DAC is unique in its stand-alone SACD (Super Audio CD) bit stream and an external digital filter interface to provide users with a great deal of system flexibility.
The device supports 24bit, 192 kHz sampling rate, suitable for high-end DAC, DVD audio, home theater, car audio, digital mixing consoles, digital audio processor.
 
Digital receiver chip: DIR9001
TI produced DIR9001 digital audio receiver chip. Very Low Jitter System Clock Output (50 ps Typically).
This chip is compatible to the highest 96KHZ sampling frequency of audio data signal, its interface is compatible with any type of delta - sigma digital / analog audio conversion devices.
Ultra-low jitter to making Dir9001 have very nice voice.
 
USB DAC chip: TE7022L
Decoder chip, SD-650 using the Galaxy Far East Corp. the latest TE7022L chip, which is the most high-end USB decoder chip, support 96kHZ/24BIT?imported and expensive.
USB mode to 24Bit frequency, the chip supports USB 2.0 Full Speed, and USB Audio Class 1.1 specifications, such as connected to the computer, you can plug and play functionality, so that simplifies software development time, there are more good sound quality performance.
 
Operational amplifier chip: JRC5532DD
JRC5532DD is Japan JRC company in one generation classical op-amp NE5532 based on the king of the new improved design of high precision low noise audio special double op-amp, sweep the original NE5532 high bass extension and loose enough, and ensure the intermediate frequency of sweet, each frequency band performance more comprehensive, low voltage state performance even better, not comparable to OPA2604, is a high performance to price ratio of the musical and good luck put.
American professional card manufacturer M-Audio products used in great quantities this chip.

 
Filter capacitor: SPRAGUE
To make an upgraded version of the SD-1955 to be able to get the best sound effects
SD1955 + use the top of the filter capacitor - SPRAGUE, which is one of the world's best electrolytic capacitors, the price is very expensive.
SPRAGUE capacitance thickness of the texture, dynamic, low-frequency common electrolytic forefront.
SPRAGUE is the DAC of Europe and the United States the highest rate of an accessory.
 
SD-1955+ also use Nichicon, ERO, DALE, PHILIPS, Panasonic, Raychem, gold-plated RCA, Immersion Gold production of circuit boards and other selected components to ensure that SD-1955 using the best components, the best design, the most rigorous process, the highest cost-effective design.
