I am wondering if anyone can tell me if upgrading your powercord really makes any difference in sound quality. I am using a stock powercord with my equipment now and am wondering if I should purchase an Audioquest cord because I just bought Audioquest cables and interconnects. These made an unbelievable improvement in the soundstage and I was blown away. Could a powercord really help? I am also wondering about the actual outlet. I saw that PS Audio makes a replacement recepticle. Would this help my sound quality and how? Thanks
