Can a simple DIY volume knob replace a pre-amp?


If I have only a cd (single source, can I make a simple volume knob instead getting a pre? Since it is simpler and "pure", will the sound better? I know Pre-amp will do some gain on the signal, what is the benefit to have that gain? I am shopping for a pre-amp and come across some people said that a simple volume can replace the pre. Thanks.

Thanks Gmood1, if I want to built one for my own, where can I get those parts?
I also find a company call Placette, they make some passive pre-amp with remote control (that is very important!). Did anyone try that?
