Very little.
I have 5 lb. Class D amps that sound a lot better to me than many 60 lb plus amps. I did end up with a heavy integrated, but this goes to show you that weight alone is not the issue.
Unfortunately, weight and physical size are equated with value, so of course, mega amp makers add as much heavy metal as they can.
In a linear amp, you DO want the beefiest transformer you can get, but you can’t really separate that from the weight of the chassis, nor can you evaluate that in light of the rest of the circuitry.
Get the cheapest lightest amp you like the sound of. :)
