Not only have I found from personal experience that weight is a teller of performance with amps, it is also true of preamps, cd players and DACs (but not for tonearms and cartidges). However, just being heavy does not make a product sound better and just being light doesn't make it sound worse.
There have been several mentions of class D flea weight amps. Having owned some of these (and actually currently still do), I can tell you that every single flea weight Class D powered amp would perform better with better power supplies and energy storage and with these needs also will come the weight.
It should be pointed out that for the most part, the mostly highly regarded class D amps are also the heaviest. That should tell you something!
I can invariable pick-up a DAC or CD player and just by weight tell you if it really has the potential to be great (not just average, but great). If it weight 5-10 pounds it aint gonna be a world class contender! An just weighing 50 pounds doesn't guarantee it will be world class. But at least I can look at weights and know which ones to throw out with the bath water as not up to requirements.
Every component benefits from the highest quality power supplies. Unforunately, the highest quality power supplies in terms of audio performance come with a lot of weight.
