I believe I have found the problem. I don't think it was ever the source, even though I'm sure it may be holding back the DT-880s, but it was the kind of music I was playing on the DT-880s, which does not show off its strengths.
I did change the source though to my dvd player, just to see if it could be a better match. Anyways, what I was listening to before, was like mellow rock/acoustic stuff and some alternative. However, I decided to change it up, I don't listen to much metal but, man I put in Metallica's Garage Inc. album, and when I got onto track 6, Am I Evil? I felt like I had entered some post apocalyptic, world. I could clearly hear where every instrument was in all its brutal glory. The DT-880s are best suited, for technical, fast, metal. Which is what they sound like to me brutal, cold, steel.
Switched cds to Ozzman cometh and noticed more positive results. Guess, I'm going to have to listen to more metal or change cans.
