Enjoy the real configuration dialog (you'll need to change your settings from defaults again), and enjoy the new pattern visualization, whose renderer was carefully ported from the official OpenMPT XMPlay plugin, to a UI Element of my own design, based on the foo_gep SPC visualization's design. It takes system colors, or foobar2000 Default UI colors, based on background, selection, and text colors.
However, pressing on the top of the DAC (avoiding the tubes or at least the tube holes if the tubes are removed) does not seem to alter the hum at all. What does appear to alter the hum somewhat is removing the chassis altogether (i.e. leaving only the base and the front plate). When this is done, the hum is less and possibly below the threshold of being a problem. If the casing were then to dampen this sound further it would likely be OK. The problem is, the casing appears to worsen the hum.
Whilst I remain keen to address the root cause of the problem, if there is anything that can be done casing-wise then of course I would be keen to try it! As mentioned earlier, I tried putting a rubber washer in-between the 2 screws that fasten the chassis to the front panel, though this did not alter it. I considered putting washers in-between all the smaller screws that hold the casing to the base panel, though this would be extremely fiddly to do.
OK- if you are alright working with the unit while the case is off, if it were me I would be using a plastic straw and probably also a light metal rod, each pressed against the power transformers in the unit, with the other end at my ear. IOW, using them as a stethoscope to see which transformer is making the noise.
Once you've done that, report back with any findings.
Have you contacted the manufacturer regarding this issue?

Removed REM from composer but then the CUE didn't read.
If the hum is really annoying to you, I suggest you cut your losses and buy something less exotic. You bought something exotic and you got exotic problems.
Seriously... vacuum tubes have been obsolete since the 1960s (although guitar players still like tube distortion). It's super-silly to put tubes in a DAC. There are DAC chips that don't need any additional active electronics in the signal path, although you might want an op-amp buffer on the output.
I don't have a separate DAC but I've got a $20 USB soundcard and a $300 AVR and there are no "sound quality" issues. I've got a couple computers with no sound quality problems but they do have audible fans and that might annoy you as much as the hum .
edit: I just tested it out: Spoiler (click to show/hide)
- install wine (any version really, it's been working for me for several years, I'm currently using 3.0rc6) - install wine-mono (or whatever it is called on your distribution) - create a new win32 prefix (WINEARCH=win32) - install dotnet20sp2 using winetricks. It shows a couple of errors (i.e. "mono not installed", even though it is), but the process finishes fine - install vcrun2008 - copy the CUETools folder to your prefix/drive_c/Program Files/ - launch CUETools.exe with WINEPREFIX set to your prefix
It takes a while to launch, but it does launch fine. The only problem I had was that configuring it as I wanted crashed on some steps. What I did was configure it as I want on a windows machine, then copy the settings.txt to my linux one.
I've also created a desktop file for each of them: CUERipper:
Thanks, after tinkering a bit with wine and playonlinux I got CUETools working with no problems. Fortunately I had my old windows config from the days of winXP floating around with all my presets and everything...
Before this I was running it with mono on linux, but that way only works with WAV files, now I can save an extra step of transcoding and some tagging... and verifying in one step is much easier.
As you can see : - The "2017" in the header is dimmed in SimPlaylist, when I didn't ask for it - The "(Interlude)" (track 09) and "[Bonus / Panda Remix]" (track 15) are more dimmed (hence difficult to read) in SimPlaylist
My formatting codes are apparently identical in both cases. So why is SimPlaylist acting this way ?
