SN#760 here. Ringing has only ever occurred for the first 15 seconds after turn on and when plugging in phones. Since I leave my main phones plugged in most of the time, ringing has never been much of an issue for me.

#000671 here, the ringing became apparent when the tubes got erect, tried sticking them back on the board to no avail, even tried to gently bent the leads... I just left it as is, and try to be as still as possible when listening...

  Currently, I'm hearing ringing when I even touch the volume pot, and often just when I move in such a way that jostles the headphone wire. I'd read about the tubes coming off the foam during shipping, so I checked that, and both seem to be fairly firmly planted on the foam, but I gave them a gentle pressing anyway, and the ringing is still pretty strong and long-lasting. Is it time to contact Schiit about a replacement, or should this ringing lessen with burn-in?

 
I contacted Schiit about the ringing, asking if this was within the acceptable range. The first response was that, if it dies out in thirty seconds, it's acceptable. I responded by saying that, well, it's still faint but present from 30 to about 40 seconds, but the more pressing concern is that if I move the headphones a little or the cord at all, it rings. If it's acceptable, it feel like it's on the outer limit of acceptable. They immediately offered to swap it, "just to be safe." I put it back in the original box and dropped it at a FedEx location.
 
Three or four days later the replacement arrived and it is a SIGNIFICANT improvement. I'm pretty sure I could do a jumping jack with the headphones on and not have any trouble. The volume pot only rings when I unexpectedly hit either the high or low limit (that is, with a bit of momentum behind the twist), and tapping on or around the unit doesn't trigger anything. I was even able to plug the headphones in gently when doing some A/Bing with another headphone amp last night and only trigger ~5 seconds of ringing. With the first one, plugging in, no matter how gently, gave me extended ringing.
 
So props to Schiit, for fast customer service and for taking my word!

^ glad to hear your problem solved. That also gives more confident for Schiit commitment to their customers.

Just wondering if it is possible to use some copper wires to band the tubes to the foam in order to resolve the erection problem?

In my case the foam itself came loose :|

Just bend the leads to the tube gently so that it's perpendicular to the board and then push them down again

Sounds more dangerous than pushing the tubes down to the board directly...might break the legs

Hi All. I'm new here to the forum, a long time lurker though. I just ordered a Vali and am looking forward to it. As a long time Guitarist and Builder of Guitar amps, I'd like to give a Little insight as to a possible cure for this "Tube Erection" problem that some of you are experiencing. Has anyone tried pushing down the tubes onto the pads, holding them in place with a light Clamp or tape and then apply a Little High temperature Silicone sealant on the underside of the tube tip or body and Chassis? I think once dried it would securely and safely hold the Tubes down more or less permanently. It works well in guitar amp applications. Hope this helps.

Had my vali # 000356 for almost 3 months now and I love it.  Ringing is a non-issue, since it is only audible for about 5 seconds when i turn it on and I leave my HE-400's plugged in.  I have the vali set at 12 o'clock and use my comp to adjust volume and it gets too loud by the time i get to about 50 out of 100 on my computer volume.  Seems to drive my 400s very well.

Yes, sounds logical. I haven't opened mine up to look at that practicality but seems sensible (regarding holding the tubes down w silicone).

Cheapest option is Fiio D3 at $32, assuming you're using optical out on your TV. If you're not using the TV for music (but for movies or gaming or anything with a visual presence), I'd say the D3 is fine. You're not gonna be able differentiate the subtle nuances of DAC when most of your attention is focused visually.
