Why not go back to no pre-amp? If this was pleasing before, it seems to be the cheapest solution. If you want to begin spending money to upgrade, then thyou have alot to work on. I know your McIntosh amp quite well as a buddy of mine had the same one. I would start with that, cables next and finish with the cd player. By the time you got to this point the Creek will sound fine.
I do not hear you wanting to go this route, so again I would go back to no pre-amp and enjoy the music.
