I haven't gone this long (almost 2 years) with the same rig without going through the itch for something new. In fact, I have been so content with my tunes, that I'm not even entertaining the idea of listening to Zucables new Definition 2. Sure, it problably aces my Def 1.5 and is affordable, but I'm still in sonic nirvana. Sure I could do better, but there is no itch...and that's a good thing: to be content with what I have.......warren :)
