tube buffer?


if you use a tube buffer with your cd player please help me understand to what advantage (potentially at least). I am a novice,still in the early stages of learnin'.I have a Rotel RCD1072,and NAD C372 integrated.Many thanks!

Gmood1,I appreciate your detailed response.It has led me to more research,(which is always fun).Thanks!
Not an expert here by any imagination but I hooked my Arcam CD 72 to Musical Fidelity tube buffer, also have the associated MF outboard power supply, then to my Panache integrated and for me anyway it seems to add more detail and resolution to the music.
if a tube buffer has a circuit which is responsive to changes in tubes, you may be able to tune your stereo system to your taste.
