How good's your hearing

As is so often the case, follow the money.   Ask yourself, does the individual bashing something need you to be convinced so he/she can sell you something else?   If their mortgage depends on their ability to make you believe what they need you to believe, you're better off getting  your guidance elsewhere.   And if they can't pay their mortgage selling you a Class D amp, well of course "it sucks".   But what they really mean is that it would suck if they had to live out of their car, so please believe what they tell you.
