My 2 channel system consiting of a NAD C370 integrated, Denon 3910, and Tyler Linbrooks has lost its mojo. One day I was in sonic heaven, then I tried using an Audioquest Viper cable instead of the jumpers on my NAD, left it that way for a week, decided I didn't like it as well and put everything back the way it was. Now no mojo. I can't put my finger on exactly what I don't like as the imaging is still excellent, sounds are coming from where they should be, just seems like the mid range is too forward, bright and overbearing with vocals. I'm going to double check everything this weekend. Heck, maybe I've just hit the point where my brain says I'm tired of listening to the same equipment.
