Selecting audio components

I'm trying to figure out which set-up would sound best cosidering I listen to alternitive music( loud rock n roll ). The choices are: Theta Miles directly into a Krell or Mark Levinson amp or a Krell KAV 300 cd player/Krell KRC-3 OR HR combination? Or possibly the Theta with the KRC preamp. I don't necessarily have to have the preamp but I would like to listen to my Magnum Dynalab tuner. Any suggestions as to which combination would sound the best would be greatly appreciated. I will also be using Cardas power cords,balanced interconnects etc.
