You mentioned on a different thread using a dental pick to tighten the socket contacts on the Vali. Care to elaborate on the process?
Mines had enough tubes in and out of it that its starting to resemble an aging pornstar. Actually, the contacts do still feel tight, but it does seem to hum more now than usual. Tried cleaning tube pins to no effect. Maybe time to look at the socket…
What I do is simply stick the end of the pick between the metal contact in the socket and the ceramic/micanol/plastic of the socket base and gently pry the metal contact in slightly. Just pry gently to avoid collapsing the metal -- you can always retighten, but not un-retighten. After you do it a few times you'll get a feel for how much pressure to apply, and octals will require a bit more pressure than novals due to the (usually) thicker metal of the contact.
Perhaps a picture is worth a thousand words. This is a split contact socket, but the process is the same regardless of the shape of the metal contact:
It can, if you can get the tip of the pick between the edge of the metal contact and the ceramic. If you can't get the pick in there, you might try a sewing needle. Just pushing it between the contact and ceramic will tighten the contact up.

Y'all are a bad influence. I picked up a Matsushita / National PCC88 / 7DJ8 from Upscale Audio. Plugged into my Vali 2+, driving Grado Hemps. Sounds absurdly good. That's my highly erudite opinion... ridiculously good.

I bought a vintage Sylvania, based on recommendations in this thread. I am baffled at the sound quality I am getting from a $150 amp + $15 tube. It sounds fantastic with everything I connect to it.

lol yeah my concern is Mimby is actually hotter than Vali 2+, just don't want the plastic feet to melt LOL. Or like not being able to dissipate heat properly, I'm assuming they picked metal case partially so it can dissipate heat quickly.
Though Mimby being an R2R dac I think actually likes heat I think. But good to know it's perfectly safe to stack them!

I found the Matsushita a little bit dark for my taste, but maybe it help tame the treble on Grado Hemp??? (haven't heard the Hemp yet so I don't know how much difference it is between the typical Grado sound)
