Interestingly, you can make a pretty good instant assessment of the quality of a piece of pro audio gear by its density relative to other devices of the same function. Denser is better, until you get up the the very top of the price range when density suddenly drops due to a switch in the tech used, eg. digital amps.
I'm curious as to weather or not this is sarcasm? I remember the owner of a small company that makes top of the line a/v equipment (the type of stuff Saudies wih oil money put in their private jets) come talk in one of my college courses. He showed us the inside of a case, and where they added weights on the inside, so it felt 'solid'. And thus sold it at a premeimum.
p.s. I'm a horrible speller, Somebody make a keyboard app with a spell checker, eh?
It isn't sarcasm. Good quality pro audio gear weighs a ton. I know this because I've schlepped lots of it around. I've seen enough of it opened up to know that it doesn't have weights added to it. The kind of people who buy this stuff often open it up as soon as it comes into their possession, out of curiosity. Any brand adding weights to their products would soon be laughed out of the market.
Good quality in this context doesn't necessarily mean audiophile sound quality, it means consistently high performance and low failure rates over many years of abuse.
As I said, when you get to the really top end stuff, it stops holding true. Weight is the last thing to be optimised as you go upmarket.
This is pro audio gear I'm talking about, not so called "high end" consumer stuff. I mean the stuff which has rackmounting brackets, not the stuff with a delicate finish. "Audiophile" kit is synonymous with snake-oil, as that guy who came into your college demonstrated.
