The MOVs are a very good thing, they take the hit of voltage transients that would flash over he X capacitors across the mains. I've always joked that X capacitors are a form of dosimeter - by measuring how much capacitance they have left, you can assess how dirty your mains is as far as transients go.

Those filters look quite good. Such things also work both ways, they will keep the noise from noisy gear from getting onto your general supply. Once this was important, but it's a bit of a lost cause nowadays. Still it's a good idea not to have anything noisy on the downstream side of the filter along with what you're trying to protect.

It's always the soundstaging which goes first, however if you switch over to the right sort of electricity, it can be made a lot better. Go for wind and hydro power. The much larger total rotating masses (and the moving water mass) make them much stiffer supplies than gas and steam turbines, consequently the supply is less effected by the demands of audiophile amplifiers. A simple change of contract and you'll be able to post about an awesome improvement. The only drawback is that you'll be forced to listen to all your records again. 'Irreproduction" the journal of high-end subjective superiority said it was at least twice as good as running an especially expensive green pen round the edges of all your LPs.
