    I have a my computer connected ISO Regen feeding my DI-20HE with the above Uptone adapter. The Vbus switch is permanently off for me, I never have to turn it on when restarting the PC or DI-20.

    do you have pci-e usb card for audio output by usb?
  3. darren700
    Yes I do. SOTM tX-USBexp powered by ebay Minishow 7v LPS. I lucked out and picked up the SOTM card used for a really good price.
    It is a recent addition and definitely an improvement from the motherboard usb,, but with the ISO Regen my motherboard USB still sounded pretty good.

    @PLGA - can you provide a link to the AES cable? If I end up getting a DI-20 - I might need a good AES cable. My DAC only has SPDIF and AES. No I2S, so for better or worse - less options to torment myself with :wink:

    I guess that's the 2nd vote for AES over Coax! (I do have a very good WireWorld Coax cable, though)

    Get a Belden serie fe 0.3m hdmi from BlueJeans cables. Best sound yet.

    Fred - where do I plug the HDMI cable to?! My DAC does NOT have I2S... :wink:
    I have: USB, TOSLINK (optical), SPDIF (RCA / Coax) and AES.

    Sorry. Than the dh labs d110 (aes/ebu) is great for about 50$ if you can solder, make it 100$ otherwise.

    I would go with the DH Labs cable as I think is a well regarded brand. I personally have their bulk AC power cords (Red Wave and AC Power Plus) and I think they are great for the money. I havent tried their AES/EBU cable, but it must be good and I think Fred has more experience trying cables than me.

    On the other hand, the chinese cable I have will cost similar to the DH Labs one and, even I like it very much as XLR and then as AES/EBU, from an Aliexpress seller you are never 100% sure on what you get. I think the DH Labs will be a safer bet.

    I was having some issues with my DI-20 usb input so I refreshed the Amanero firmware. Now it works with the data line only even for the handshake.

    Please forgive me for any misinformation earlier...

    I have found total happiness with my updated setup:

    Usbridge signature (fed by ebay minishow lps optimized for rpi using a ghent canare dc cable) > ebay silver usb cable > di20he > BJC belden series fe 0.3m hdmi > r7he > diy silver litz acss > he9 > diy silver litz acss > master 3 > acoustic zen satori shutgun > Osborn Eclipse with ref tweeter

    That’s it.

    Forgot to mention i still use the ebay external ocxo and the serial mode on the di20, the ocxo being fed by an ebay minishow lps through a ghent silver-plated dc cable.

    An update to my “phantom-out-of-phase-micro-bursts”. I tried serial mode which seems to thwart the problem...except serial mode with C16 external clock sounds quite poopy compared to parallel mode...pretty much a non-starter. Has anyone who communicates with Kingwa brought this to his attention, since more than a few of us are experiencing it? Now that my HE has a little over 600 hours on it it is really starting to sound like the piece of gear I was hoping for...EXCEPT this random phase anomaly...which really is quite annoying.

    I would also like to publicly thank Wynnytsky in advance for his generosity.:thumbsup:

    I contacted him. Some users have the issue, some don't. I am waiting for my second ocxo to come in before re-contacting him if the problem remains. Try the belden hdmi, works great for me in serial mode.
  14. FredA
    Plus the difference between the internal and external becomes small after 800 hours, bass digs lowers, the rest is pretty much the same.

    Just realized i was in serial mode, there is more of a difference in parallel mode. So far, no glitch with the external using the Belden hdmi. Crossing my fingers.

    Dam glitch still there.
