I just upgraded a few of my cables. I had Monster THX Ultra 800 audio interconnects (six channel) from my Denon universal player to my Denon 3805 receiver. I also had Monster Z1 speaker cables. I changed them for the Nordost Wyrewizard interconnects and speaker cables. BIG difference! I cannot believe that this simple and not to expensive upgrade, yielded such great results. The Wyrewizard products were not that much more expensive than the Monster cables, but are much better. Has anyone else upgraded from Monster and "heard" a big difference? Has anyone else tried out Nordost's Wyrewizard line? Your thoughts.
