new digital source

I just recently purchased my good 2-channel setup and now I'll need to pick up a digital source to go with. My current setup is a VTL 5.5 pre, VTL 450 monoblocks and Dynaudio C1 speakers. I want a digital source (it can be either CD player or DAC) that I'll use mostly for rock/metal (any other genres will be listened to on my turntable).

What I'm looking for is a big, deep soundstage and the instruments to be very clearly separated. I want to make sure that the double bass drum sits at the back, all the cymbals are clearly heard in the right spot, and the guitar(s) are clearly audible. I find that in the lower-end sources everything becomes a mess with fast songs, like most metal, and all instruments are hard to distinguish.
