    Hi.
    Have these interfaces a direct internal power supply  (without USB) and I2S output ?
     
  3. ccschua
    pls compare with diyinhk pro4A.
     
  4. rb2013 Contributor

    No direct power feed - but there are many solutions for USB power - I'm currently using a PUC2 Lite and a DIYinHK DXIO Pro3a.  The PUC2 lite has USB power only - the Pro3a can be powered either way.
     
    I don't use I2S for my DACs- only SPDIF - but it appears that they have the pins out on each board for I2S.
     
    Here is what has worked for me on the USB powered DDCs:
     
    So far the best is the TeraDak DC-30W/Cerious/DC iPur to the Regen then the iPur2.0 to the PUC2
     
    the next best the iUSB2.0/iPower 9VDC/DC iPur/iPur 2.0,
     
    then the 5VDC iPower/DC iPur/Pur 2.0
     
    Note all using a JB at the PPA2.0 modded into a VBUS blocker (and power and ground pin severed). 2G cable (no power leg with the Regen).
     
    The iPurifier 2.0 relocks so need to be powered...now getting ultra low noise +5VDC from the Regen.
     
    Each level of AC/DC filtering has opened up the sound - just shows how awful our modern day electrical grid is - digital noise pollution is horrendous.  cleaning the power is especailly noticeable on digital chain.  With all these femto second clocks - super sensitive to jitter effects and PS noise of many kinds.
     
    Edit:On the i2s - "Screw position, I2S pin position is fully compatible with  Italy Amanero module."

    Well the X1-S is similar - but has the better XU208 vs the U8
     
    The F-1 XU208 has chip based noise isolation (CPLD Xilinx) for SPDIF like the Tanly (Spartan FPGA) and Hydra Z (Atmel FPGA?) - and looks like a unique USB chip based isolation system on the board.  Won't know more until the board arrives and I can get a closer look at the dual large chips in the middle.
     
    Also has multi LDO ultra low noise regulation via the ADI LDO's - but again will need to see which exact chips used.
     
    Here is the U8 based Tanly:

    Hydra Z:

    Note both use FPGA isolation and Crystek CCHD-957 audio clocks.

    i saw this one month ago at taobao,
    if only they have finished product not diy like like this i will buy without thinking
     
     
    so this f1 board does it need any transformer like talema or murata
    or just plug it with usb then the coax out to dac?
     
  8. hugoboss
    oh my god i just check taobao they already have finished product but it costly man
    very costly compare to melodius or gustard it cost $300
     
    here is the pic

    SU-1 digital interface of our team to develop a high-performance USB digital audio interface, using the XMOS latest xCORE-200 series chips. SU-1 is a self-developed ultra- low jitter clock system ( Crystek of CCHD-957 series ), with astandard USB2.0  input interface, rich output interfaces, including XLR balanced output AES, coaxial RCA and BNC, use HDMI socket output I2S interface output word clock WCLK.

          SU-1 long-time research and development for nearly a year, which has gone through many twists and turns and variables.

          SU-1 is the first machine we have developed equipment that is positioned in the high-end interface, is used mainly in the following three main technologies:

          1, full isolation technology (ground isolation), the use of 150Mbps full-chip isolation, interference can be completely isolated from the PC;

          2, source synchronous shaping technology and CPLD technology, I2S signal isolation after the re-shaping; thus eliminating the isolation chip to bring added jitter;

     

          3, the independent development of the system clock, using CRYSTEK high-performance oscillator, low phase noise and low jitter.

     
    plz somebody tell me is the hdmi i2s output support audiogd master 7?
    god this is so fast!!!

    This board takes it's power from the USB +5VDC leads - many ways to cleanly power it - as I spelled out.  Like the highly regarded Yellowtec PUC2 Lite.
     
    Right now my PUC2 is fed from a Regen (which has on board 1uV ultra low noise regulators) which steps down +7VDC to +9VDC incoming voltage to +5VDC out, besides relcocking the USB data stream and impedance matching.  The Regen has a 2.5mm ext power feed - I'm using a linear power supply TeraDak DC-30W filter with a iFi DC iPurifier.
     
    This power chain is much better then either the on board AC to DC power supplies of the Gustard U12, Melodious or the Breeze Audio.  For one the TeraDak uses an R-Core transformer vs the Talema Torodial - much better noise rejection.

    Nice find!
     
    The SU-1 is basically a F-1 board with it's own AC to DC power supply - would love to see one with the cover off.  For example which transformer they are using - power filter caps - any additional PS regulation besides the ADI LDO's on the F-1 board. 
     
    Got to get me one to try - but with shipping $350!  Still half the price of the Tanly...
     
    And this...
    Does have it have switchable voltage like the U12 to 110V or 120V?
     
    The advantage of the F-1 is you can feed it a very high quality linear power supply by simply using a split USB cable like the Lightspeed 2G and a linear power supply like the TeraDak X-1 or DC-30W, Paul Hynes (the ultimate!), Tedy Pardo, upcoming Uptone LPS, etc...
     
    Still curious about how they do the:
     
    That is the first I have seen of that technology built into a DDC - maybe the Berkerly Apha USB...

    Does anyone know if the su-1 aKA SINGXER HDMI I2S SUPPORT Audio GD master 7 hdmi i2s input without any modification
    thanks very much
     
  13. abartels
    How could we know if there even is NO info available right now? If they have some sort of connection scheme to share with us,
    yes, then we could tell you if it's compatible with M7.
     
    Maybe you could opt asking Kingwa to contact Singxer and confirm it is compatible.

    Does the Audio GD Master use the Amanero i2s pinout?  This was up on the original F-1 ad I bought from - should be the same for the SU-1 as they are both made by Singxer "I2S pin position is fully compatible with  Italy Amanero module"
     
    Very excited - my boards should be here next week.  The EMS package went out a week ago.
     
    Checked on Computer Audiophile's threads - nothing on either of these new devices - in fact nothing on the XU208 (unless I'm missing some thing).
     
    Breaking new ground!
     
    The F-1 and SU-1 150Mbps USB isolation looks very interesting - the Tanly and the Hydra Z use something similar I believe  - both twice the price.
     
    I'll order an SU-1 today to compare.
