Exactly. That is the point.
@Golf - when told that only measurements are a reliable predictor of sound quality, suggested weight as a suitable measurement. It is (obviously) not.
It suggests design choices (eg, machined from solid case, linear power supply/big heatsinks etc). However, as long as a design has a stable PSU or whatever topology, and the cooling design is sufficient (no matter how achieved) then weight is irrelevant to sound quality.
Further, it has been pointed out, that some designs include heavy components seemingly just to increase weight to create an "impression" of quality. In today's world it could be argued that linear power supplies and big heatsinks are just that, even ignoring the use of objectively oversized components in some cases.
These points seem to have passed him by.
