if you want optimal sound quality, avoid all magnetic materials
and keep all kinds of metal far from trafo
not even copper, no nothing

now, if you have severe noise problem, then may be different issue
and I guess most of us have
in these times with computer switchmodes everywhere

If that would be the case you can't even mount a toroid in a metal housing...
There's no magic involveld with shielding transformers, some manufacturers have "audio grade" toroids with grounded metal film shields at the outside.
Noise problems with toroids are often caused by harmonics on the mains and because of the high bandwidth of toroid you also see them secundairly... Odd harmonics on the neutral of the mains (3rd, 5th etc.) is indeed a problem, and the only solution is filtering (or throwing out all inverters, led lighting, also at the neigbours )

That really depends, but it's always interesting to try and see what you get.

It will definitely change the sound character, the only question is whether
you will prefer it that way.
