If CD playback is your only source then you'll just need to get an expensive CD player with high output + volume control. In this case, the "less" component is better off.
I copied S23chang's post not to necessarily single him out and disagree, but because his comment is so germain to my situation.
I own a fancy shmancy digital player with built in volume control, and I have found that I prefer the sound of my system with a preamp in the chain. This preference has been consistent through several listening sessions with four different preamps. Other owners of the same digital player swear by going direct.
I suppose this illustrates that there are no absolutes, and one needs to listen for oneself and choose what he/she prefers.
