I just finished 2 hours of listening to my system and it was the best I've ever heard it. The main change I made a couple of weeks ago was an IC (see October's issue of Affordable Audio e-zine for the brand and review).
In the past my motivation for new gear was to hear the proper tone of every instrument distinctly, and at one point I got there. But I knew there was something missing, so I kept searching. Then I finally stumbled upon what I really wanted to hear -- music.
At this point you may be saying, "WTF is he talking about?" Well, if you listen to live music, you're not gonna necessarily hear every instrument distinctly. The instruments ebb & flow with one another along with the vocalists. There should be "synergy" here, not just singers and musicians jammin' together. Yes, I realize this sounds quite rudimentary, but sometimes, in the midst of our weekly tweaks, we forget what music is really supposed to sound like.
But the biggest impression my "new" system made on me this evening was the emotionality conveyed by the vocals. It was freakin' phenomenal. At one point one of the female vocalists made my nuts tingle. Now that's what I call, "music appreciation.":p
