ROI. Where is money better spent?


Sorry if the category is not quite accurate, but i would like the opinion of the knowledgable crew here. I am shopping for a preamp and interconnects, source to pre, and pre to amp, balanced. I am not looking for any brand recommendation, but want to know that if i had some xtra money to spend, should it go into better cables or better preamp? Thanks and happy holidays!

So far pretty unanimous. I was concerned that less expensive cables would vail or block some of a good preamps sonic performance.  But  any input( no pun intended), is appreciated!
Cables are like spices to a degree, they will season to your preference but not make up for a lessor dish.  
My experience lately is getting good preamp then later good cables these compliment each other. I never new how good is my art audio preamp till I bought a very good interconnect  and speaker cables..,,
Better speakers, then Better room treatment.... then better pre. :) ;]
