Would you tweak this phono amp?

[Poltergeist]

I just bought a Primare R32 phono amp. It got plenty of space inside and I thought that I could do something about it.

The most obvious thing to do would be trying to damp the wall in the middle. But how?

And are there other things that could be done at the same time?

Questions, questions.

What would be effect of it ? On which part(s) it would cause some...?
If you mean vibration and resonances, just partitioning it in two parts it should halven its main resonance frquency
A dampening would have a broader effect.
