Haha. Yeah, I did mean the Denon D2000. The first thing I remember about my D2000 (if I remember correctly) is that it had rock solid bass, though its piercing treble got to me soon enough. I got D5000 cups for it and it sounds a bit warmer now. Probably my second favourite pair of headphones, but its bass isn't as solid sounding as before - which is fine depending on how tired I am.
edit: Alright, tried out the Pro 900 for a day and I am back to my D2000 with D5000 cups. What was I thinking?
Edit2: however, the Pro 900 really does sound quite good straight out of my iPod Classic.
