I'm mixed on this topic, but tend to side with Jaybo... wait a while first.
Philosophies vary on system building around here. I prefer to go from front to back myself. Especially if one is not tremendously flush to begin with... which bars buying top flight speaks right off.
If you haven't yet made your mind up as to which way you want to go ex. Tubes... or SS.. and have a burning desire to spend $$$$ right now.... I'd say go get yourself as good a source as you can do.
CDP or TT. Or go the PC and/or server route.
but for now, a better source would be my take, IF you absolutely gotta buy something.
'Course, buying some music too would be in order as well.
yeah.. source.... and maybe, if you can, some cables.
