I was calling around to a couple local shops and was asking about dvd players. At one shop the person I spoke with was tring to tell me that a dvd player needed a huge power supply so that it would have enough power to output true black level signals. This sounds like a big load of [email protected][email protected] I can see why a very clean power supply maybe needed (and thus maybe a heavy power supply), but to say a lot of power is needed makes no sense. He started to draw analogies to receivers having huge power supplies. Is this just another stupid sales person or am I missing something?
