    Can be fixed by flashing a new program on your MCU. I did it on my di20he. Your need a pic programmer and patience. Or you can ask Kingwa to sell you the chip with updated program. Or you could buy such an MCU and send it for programming to a headfier who can do it.

    No problem. I use the linksys lgs-105, which is found in the lhy sw5. An ebay ultralow noise psu with chokes and an encapsulated Talema and a short silver plated and shileded Ghentaudio dc cable. I tried 3 different dc cable and two psus before getting this winning combo. I just can't believe it.

    Audio-GD Master 9

    I guess you made the hp inversion test and it not your ears causing the issue... Reason for asking is that this sort of problem is extremely rare to my knowledge. A relay or relay driver is likely deffective. I doubt a resistor has failed. Could also be a transistor issue but i doubt it. On a...

    I have the afterdark trifecta with square outs. The HT is a clear upgrade from the c2, which sound like a cheap cable in comparison, i would dare to say. It needs 4 days to start to sound as it should, but then it is really good. I will likely get an Habst soon. The HT made me realize how...

    Make sure it is not the headphones. Maybe Underwoodhifi can do it, they are the us retailer.

    Thiw usbridge signature, if you have some hands on with installing and configuring sw (although it can be ordered with the sw of your choice pre-installed) . It is significantly better than the mac mini. You'll need a 5V psu to feed it and a dc cable. The Shanti which they (allo.com) propose is...

    If you have a great ddc to go with it, it should really perform very well. So worth buying as far as i can say. You can consider upgrading the clocks on it, although not mandatory. I love the pcm 1704uk sound. You can consider having accusillicons installed in it. This would bring resolution up...

    You need a pc running Windows. Then click on this link on audio-gd to download the file and procedure http://www.audio-gd.com/Firmware/AmaneroforLinuxEN.htmH Within the update guide, it is said to short pins on the Amanero board to erase the fw. You need only to push the button next to the...

    Audio-GD DI-20

    See my reply above to dougms3. Also, an update to the Amanero fw, using the optimized for linux version could help. But start with checking issues like power or usb cable. A power cable with a bad contact can cause all sorts of issues. A bad usb cable as well.

    Audio-GD DI-20

    Indeed, and the bnc out is not guaranteed to work with all dacs, it is a current output. In case this is what is used. The mentioned music server has a usb audio out, it must be what is used. A likely cause is a dc offset. Can be fixed sometime with beefier power cord or else by just plugging...

    The 2020 has a clock in, normally. Look for a 50-ohm bnc connector and check if the menu is the same as what audio-gd describes in the discontinued products pages. The di20 would still be a clear upgrade in your case. Getting the usb input upgrade should be even better.

    Depends on how good the Element is. I have no idea. Getting the 2021 upgrade for the usb input would likely be an upgrade and you then would not need your Element. [edit] sorry, bad answer. The element is a fancy usb card., not a ddc. So the answer is yes. Or as said, you could get the 2021 usb...

    It is unusual but the cost is overall still reasonable. It's a competitive cable. Give it 4-5 days.

    The guys has never done a 50-ohm, am i right? So unless he is the greatest genius out there, yes. Buy the Harmonic tech instead.

    I would sell the di20 and get very good usb streamer, like the sotm sms200 ultra.

    You can try odin clones terminated with 50ohm connectors, or give a shot to 75ohm cables. It will work. Could even sound very well.

    Here is an update on the Harmonic Tecbnology 50-ohm cable. It has passed the Gustard c2 after 5 days. It is more refined, it offers better resolution, depth and imaging. It is significantly better. To such an extent that the C2 is now assigned to the ddc for good. Music is just more relaxed and...
