Up for auction is one of my Singxer Su-1 USB interfaces. I no longer need one of them so here it is (still using my other one as they are great). In decent overall condition (please see images), some light scratches on top. This normally retails for well over $300 new (I believe $349 or $399). Here is a chance to get a tested and working unit in nice condition for much less. Shipping will be with Fedex Express Saver and double boxed (well protected). Does not come with any original retailbox or a power cable, but any typical power cable will work (has the socket, see back). If you need a nice power cable, I have some Pangea power cables also going up for auction on ebay soon (3 of them, but they are short). If bidding reaches $130+, or if someone chooses buy it now,I will however throw in a bonus nice USB cable (Oyaide NEO d+, green color, 3 foot length) Specifications:Each output interface supports sampling rates:PCM: 44.1KHz, 48KHz, 88.2KHz, 96KHz,176.4KHz, 192KHz, 352.8KHz, 384KHz(I2S support all sampling rate,S/PDIF support upper to 192KHzDSD: 2.8 MHz (DSD64)-DoP, native5.6 MHz (DSD128)-DoP, native11.2 MHz (DSD256)-native(I2S output support all DSD,S/PDIF,AES/EBU support DSD64 DOP mode)Bits width:the highest 32 bit over I2S outputThe highest 24 bit over S/PDIF Design Details: ....high-performance,low noise and fast response of the LDO as the main power source.The entire board using a multi-way independent of the LDO power supply,wherein the clock even partially adopted ADIs ultra low noise LDO,in order to ensure the ultimate output performance.2.PCB motherboard with 4-layer circuit board design,make sure you have a complete ground plane and power planes, high-speed digital design methods to ensure signal integrity and power integrity of the entire board.The clock signal special treatment, the use of package design and precise impedance control,thereby ensuring the signal quality and increase the clock anti-jamming capability.Input and output signals are to follow standard design,especially USB high speed signals using a 90 ohm differential impedance control.System compatibility:1:Windows XP,Windows 7,Windows 8,Windows 10;32/64 bit,need install driver2:Native MacOS 10.6 and later,use own driver3:Native Linux with UAC2 compliant kernel,use own driver4:Android OS 4.2 and above,need support OTG functionI2S port use HDMI socket output:1.Electrical level is 3.3V LVDS differential signa.2.DSD ON singnal,5Vpower supply,CPLD has processed the MUTE signal,so do not need to process it again.3.DSD ON signal can be user-defined,DSD ON signal can be connected to PIN 13,14,15,16 on the socket.4.You can adjust the phase of PIN 1-3 and PIN 7-9 with a switch.

Singxer SU-1 XMOS USB Audio Bridge / Digital To Digital Converter (DDC). In near mint condition with all original packaging. RRP £399 approx. Please copy link for an informative review:- https://www.head-fi.org/showcase/singxer-su-1-usb-bridge.21724/reviews SU-1digital interface is our team develop a highperformance USB digital audiointerface, using the XMOS latest xCORE-200 series chip. SU1 is theindependent development low jitter clock digital system interface (CRYSTEKCCHD-575). SU-1 digital interface using standard USB2.0 input interface, while SU-1 has many output interfaces, including XLR Balanced Output AES, coaxial RCAand BNC, using HDMI socket output I2S port, WCLK /MCLK clock output. Technical features 1. The SU-1 is the first domestic and the XMOS latest xCORE - 200 series of USBdigital interface. A new generation of XMOS chip, using the more advancedprocess technology, the performance was doubled the old one U8 chip, theprocessing capacity of up to 1000 MIPS. 2.Used the high-speed whole isolation design, can beisolation between PC and interface of noise interference cleanly. SU-1 adopteda preeminent circuit design, using the high- speed CPLD/FPGA digital audiosignal for separate after restructuring, so as to make the signal afterreforming completely unaffected by isolation chip itself shaking. 3.SU-1 internal main board adopts the technology of theuniform source synchronous clock, CPLD/FPGA internal using special algorithm ofclock signal and digital audio signal phase control strictly, can ensure thatthe digital audio signal after isolation chip will not appear extra distortionbecause of the time delay and phase difference. 4.SU-1 internal was use of an expensive audio level lowjitter clock (Femtosecond clock), two CCHD -575 are from the Crystek.f5.It is well known that the weight of the core of thedigital audio is algorithm. Singxer team are occupied inthe field of digital audio for many years, at the same time we get strongsupport from the XMOS FAE team, we are on the basis of the original firmwarehad done many of the technical improvement and optimization algorithm.
