I received a second hand pair of Nordost Red Dawn 1.5 meter interconnects today. After I inserted them into the system, it was quite apparent that These cables are a little livelier as expected and seems to have done the trick. The treble is extended and has that little bit of sharpness that I was missing before. The bass still sounds deep and tight and I really didn't hear any loss of that.
Now my problem. Before I put the new cables in, my system was always dead quiet, not even a bit of hum. Now I am getting a hum in one channel (it was both until I rerouted the cables) only when the tube preamp is first turned on during the warming up process. Once the system is ready to play music, the hum is gone. Since these are flat cables, it's doubtful there is any shielding. What do you guys make of this, should I let it go and just enjoy or dig deeper?
