    I though of another option for you to use USB with a Mimby. With my Bimby I use a NAD DAC 2. It has a little transmitter that plugs into your computer's usb then sends the digital signal up to 24 bit 96hz to a little box that sits next to the Bimby. The little box sends a digital signal by coax into the Bimby. To me it sounds just as good as when I was using the coax output of my FiiO X5 into the Bimby. And having the wireless is very nice. It does not use your network wifi. It has 3 frequencies to choose from and you just match the box and transmitter. Was supper easy to set up. Just plugged it in and it worked. Keep in mind I do not use the internal DAC of the NAD DAC2. I just use it to pass the digital signal from my computer usb to my Bimby using the Bimby's coax input. Here are some links:

    Note that this review convinced me to get it because of this quote:

    "One interesting caveat to this is switching from using the NAD via the analogue outputs to the coaxial one into another DAC shows that it is a completely transparent wireless transfer device. With the NAD running into the digital input of a Naim ND5 XS, the performance is completely in keeping with the performance of the more expensive streamer and transfer at sampling rates up to 24/96kHz is seamless and extremely effective."

    I ordered mine off Amazon.

    @Kattefjaes
    Thanks for the comment above. I use optical either from my cd player as a transport to the mimby. I use optical straight from my computer to the mimby if I listen to music from my computer.
    Is going usb with the eitr between computer and mimby a significant upgrade from an optical connection between computer and mimby?
    Thanks

    It will be, yeah. Your computer's S/PDIF out will be driven by clock dividers from clocks of distinctly "meh" quality. This doesn't matter with the Gumby or Yggy so much, as they can sort it out with the onboard Vx0-fu to a large extent, but the Mimby's just going to try to PLL against the incoming signal and then suck it down. There will be general phase noise, as well as predictably periodic jitter caused by the clocks not being an exact multiple, most likely.

    Feeding it a nice cleanly-clocked and isolated signal, such as you'd get from the Eitr, or other decent source, will sound markedly better. Listen for better instrument separation, cleaner attacks, better timbre on percussive sounds etc.. The Mimby can sound pretty nice when when you give it a chance, it's a bit of a bargain.

    (Also, well-clocked and electrically clean co-axial S/PDIF is marginally preferable to well-clocked optical, but I'd hate to try and pick those differences out blind.)

    Mimby ordered, now I just have to wait for Eitr to become available. Thanks for the help everyone.

    Please do let us know how it went once you have your new toys.

    @AudioThief Good luck, then, mate. I hope the world will not burn if you use in the meantime just Mibi without the Eitr as it seems, judging by the previous page, Mibi is a junk without an Eitr. Burn those USBs!
