bundled signal wire

I know that power cords should not be coiled.   How about signal wire?  Inside my boutique preamp, surplus lead wires are bundled on top of the Jensen transformers.  Will this impact the sound in a significant way?  
That's weird steakster I've not seen excess signal wire like that why not just trim it down if there's too much as your building? May I ask what type of preamp that is or by boutique did you mean a custom build?
If you coil a pair - signal and return, then it should not matter. Best would be to cut them shorter, but coiling them is better than leaving them loose.  It shouldn't matter for power cords as well.  When you coil them you only increase inductance for common mode signal (noise) - a good thing.  Inductance for normal mode remains unchanged.
