    After rolling through a bunch of USB interfaces including 3 different John Kenny's, M2Tech Highface and Evo, Audiophilleo 2, Musiland 02 and Musiland USB 3.0 USD. I settled on the Musiland USB 3.0 as the best sounding. Made better with a Aqvox linear power supply. I've been running this for over a year and really happy. But heard about this unit and just ordered one, wanted to see if anyone has tried it.

    Looks promising:

    - Native 32 bit 384Khz 8 X-core XMOS chip. Multi-thread. USB class 2.0 Async.

    - Seperate 0.1ppm TCXO clocks, Temperature Controlled High Precision Active Crystal. One for each clocking ratio.

    - Independent Linear Power Supply. Sealing Torodial Transformer, Multiple Sets of Multi-Level Regulation

    - Four outputs: Coaxial (RCA), Optical Fiber, AES/EBU, IIS (HDMI port).

    - DSD support to 128. PCM to 384K.

    - Latest XMOS Thesycon ASIO v1.6.1 drivers, strong driver support for future Windows versions.


    Pics to follow.

    I would love to hear this!

    They're ridiculously cheap, I paid $159 shipped, on ebay!

    get out no way!

    What I like about it uses the XMOS Thesycon ASIO 1.6.1 drivers for Windows. These are same Ayre and Wavelength use.

    I hope it works well with JPlay!

    I have the U10 I bought before the U12 came out. It dumped the Hiface 2 I had been using. I am waiting to see if there is any reason for me to change my U10 for a U12. The only obvious change is the display which I can do without. I have been very pleased with the performance of the U10 and the price was laughingly low.
  7. rb2013 Contributor
    Yes, they look very similar. Two of the large blue caps in the U12, it looks like only one in the U1O. I can't tell about some of the chips, XMOS and clocks look the same.

    Did you have any issues with installing the driver? Are you running Windows 7?
  8. Chodi
    Yes, I am running windows 7. I modified the latest Thesycon drivers myself to work with the Gustard. That way I could have the latest full version of the Thesycon driver. The driver supplied with the Gustard is a generic version of the Thesycon with limited features. If you need the full version I modified just pm me. I should point out that my modified drivers I made are for the U10 as I don't have the U12.
    I contacted one of the Ebay sellers and they claim that the xmos chip in the U12 is a newer version from the U10. I have no idea if that is honest information (or if that matters). Since both the U10 and the U12 clock at the same rates I'm not sure that the seller was not just trying to make a sale. If I can confirm that information is true I may go for the new version as the cost is very minimal and I have been very impressed with the U10.

    Any idea if this works with linux?

    When I get mine, I'll open it up and take some closeups of the chips to post. I'll PM you for the driver, couldn't hurt. Thanks!

    I'm sure the XMOS is constantly being updated. One thing about the Musiland, it has an excellent monitor window with a digital balance control that comes in real handy. Does the Theyson/Gustard offer this? Do you use Jplay?
  11. Chodi
    I don't know anything about Jplay I use Jriver and Foobar but I can tell you the Gustard does not have any balance control. I would expect that to be an unusual feature for a usb converter.
  12. rb2013 Contributor
    It's really good, with control over the various outputs, vol and bal.
    Here is a screen shot of the Musiland control panel.

    I was hoping the Gustard offered something similar

    Here is a great site with lot's of useful info on the XMOS 32bit USB chipset and Musiland 3.0 USD (pc inteface) and Musiland 3.0 US (DAC and interface)
  14. Chodi
    Oh, you were talking about a software control. Yes in the TUSB Audio Control Panel there is a balance control. I thought you meant some type of hardware control. It is a simple left/right channel gain control. Nothing as elaborate as the one in your picture. Frankly, when I feel the need for a software digital volume control I just use Jriver internal. It works fine for me as long as you stay under 10db change I find the results to do no damage.
  15. rb2013 Contributor
    Yes, foobar has similar, but I find the 1dB fine control of the Musiland really useful. Good to hear about the TUSB control.
