Cheap/expensive or expensive/cheap?

While I was listening to my modest little system recently, I began to ponder a question. What would sound better, an expensive system with the cheap/stock cables or a cheap system with high quality cables/power cords? For example, say you have a $3000 system (total) but have high quality cables/cords/conditioner etc. vs a $10000 system with just the stock cables and original power cords (no conditioners). 
I read many topics on AG and I am always amazed how much I don't know and how much I've learned on here. I've been updating my system over the past 2 years or so and appreciate all the experience and knowledge on these forums. Thanks---I look forward to your comments.
