It's a SinglePower MPX3.

With the bottom plate removed you can easily see where the capacitors came loose. That circuit board is screwed into the frame.

There's about 1/4" or so of access space from the side where the pins of the capacitors can be reached. Unfortunately, not enough space to allow a soldering iron to get into.

That's a pretty serious looking headphone amp! Definitely an access service challenge as you say.

I took some screen shots off the web to confirm that it's the same model.

I also came across quite a long thread on another model (link below) that eventually mentions yours. Overall the brand is very highly regarded for sound quality but some caution regarding electrical build faults that may or may not apply to your specific unit. Still it should be heeded for safety reasons to determine what level of service should be done, given the rocky shipping journey.

Beautiful looking unit and I bet it sounds great. Only headphone amp I've ever listened to and worked on was my son's Schitt Vali. Much less complex though he hoped I would totally break it with my DIY skills so he could upgrade LOL.

  Yep. That's the one. The two capacitors on the lower left came loose.
  
  The MPX3 is a fantastic amp. These were built before all the issues Mikhail ran into on his later builds (too much customization and not following thru on all the upgrades folks sent their amps back to him for).
  
  I also have the Supra, Supra XLR and the Maestro ZR. I've had a lots of headamps and the models from Singlepower have been the best, to my ears.
