That's a bit strong, Merlin. Nothing wrong with being happy with your system, shite or not. Mine isn't, BTW (shite, that is), and I'm happy with it, what does that say about me? It's not perfect by a long way, but it plays music and gives me no desire to watch TV instead, or to spend hours tweaking it.
Power leads, isolation, interconnects, mains conditioning, separate spurs, CD anti-static devices, these are all areas of entirely legitimate disagreement, and always generate heated debate. No need for anyone to get too exercised about any of it.
