Amplifier Weight. A Factor?

I was responding to Porziob, who feels they offer poor value, I am fully in the opposite camp on that...

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.

I think it was audio magazine years ago that provided a watts per pound per dollar assessment of amplifiers. It was all tongue in cheek but I bet it would support your conclusions. Are the best guitars the heaviest as well?

A guitar doesn't have a power supply. Electronic components have power supplies and the power supplies are a lot more influential in the performance of components that most realize. Of course, you have a lot of manufacturers making components and using crappy, cheap, light weight power supplies that will try and tell you otherwise, but of course their components don't typically stack up very well.

Weight seems a deciding factor with tube amps, as others have said. There is simply no substitute for big, high quality output transformers with tube amps. If a tube amp does'nt weigh 50lbs+, it will not have the base to give long term satisfaction.
Before anyone else says it, this does'nt apply to OTL amps, though they seem pretty heavy too. I bought a little!! Ayon Spark tube amp recently, it looks small, but it is a brute to move, with all the weight in 3 massive transformers in the back. Was it worth the prolapsed disc getting it upstairs? Absolutely
