Interconnects - better before preamp or after preamp?


If you have a World class preamp, is there a need to go nuts buying some really nice cables before the Signal reaches the preamp?.  Let the preamp do its thing and then provide Royal treatment for Signal‘s Journey to the amplifier.

If you had to choose between before or after a preamp what would you do?

Better cables closer to the source. The better the quality of signal feeding the pre, the better the output from the pre.

The signal is as good as it gets AFTER it leaves the source.

Keeping with audiophool philosophy-wouldn't it make sense to attempt in keeping it that way at least to the preamp? 

How does a "better" cable improve it after the pre? Must be nothing more than a tone control and wallet depletion device.
