Which cables and ics allow the biggest soundstage?

I enjoy cables that allow the music to pour through not constricting the sound and its subsequent effect being a large soundstage.

For those who have tried numerous cables, I'm wondering which ones (no more than $750 used for ic's and $1500 for speaker cables) have given you the biggest soundstage and if you think a certain type of design is better at this than others (i.e. solid core).
