You might consider system tweaks such as Symposium roller blocks, upgraded cable, and spikes. I am not sure that the ARC CD1 is the problem. I had one here a few months ago and thought it was very good.
Also, the Vandersteen 2ce speakers respond enormously to set up procedures. You might take a look at how they are interacting with the room. Sometime this is all that is needed to completely "lock in" the sound you are looking for.
