If weight is not a big issue, such as if
it were on an airplane or even a car, a heavy unit is
less expensive and longer lived-one can overspecify
transformers, put in bigger caps, use a heavier chassis.

That necessarily helps sound quality how?

Bigger xfmrs have lower flux density at a given power
throughput and heavier chassis means better shielding and
mechanical stability. That's the way to bet, anyway.

OK, bet with your money. I'll spend my time and money on
things that have audible benefits.
