I also have a Weiss 204 DAC with a Bluesound Vault. My Weiss started "skipping" pretty soon after I got it. At first, turning it off for a couple days worked but then the issue came back. After several conversations with the dealer and with Weiss, we determined that the jumper could be the issue and we should move it.
However, once I opened it up I found that it shipped with no jumper at all. Weiss first suggested I could fix it myself with miscellaneous wires wrapped around the posts, but that was very hard to do and didn’t really work. Finally, I was able to convince the dealer to send me a jumper - which only costs 30 cents. Weiss would not send the part and would not agree to an exchange or a refund.
After a few more weeks of trial and error, moving the jumper around and tryiing different DIY solutions, the dealer finaly agreed to an exchange.
The new one skips as well.
I bought a new high end ethernet cable and directly connected it to the mesh extender but that has not helped.
Final solution - I now turn it on when I want to listen and turn it off when i’m done.
The Weiss DAC sounds good but I would suggest looking elsewhere. It has a major flaw and I feel like the owner of Weiss (based in Switzerland) does not care about customer support or a quality component. I was shocked that I was told by Weiss to fix a very expensive item myself, and he would not agree to send me a 30 cent item and would not replace it. He did initially send some pictures of where I should move the jumper, (if the unit had been shipped with one) but the pics he sent didn't match my unit, so his input was useless.
