I have run both setups extensively, due to different living circumstances, once with long (20+ ft) interconnects and now twice with long (20+ ft) speaker cables.
I very strongly recommend going the route of long speaker cables. You can run long interconnects (better if balanced, but can do single ended) and there is unlikely to be any trouble at all.
However, the signal is its most robust when in the speaker cable and I now run 25' speaker cable and could not be more happy with the sound and cannot tell a lick of difference.
