Long Cables w/Short Speaker Cable or Vice Versa?


Assuming your equipment (other than power amp) is located a considerable distance from your speakers (15 feet), which is better:

(A) Long Interconnects with a Short Speaker Cable run; OR
(B) Short Interconnects with a Long Speaker Cable run?

Ideally, I want to seperate my McIntosh MC2301 monoblock amps so that they flank both sides of the cabinet built-in's that are on both sides of my fireplace and TV. Even if I put the amps together (in the left-side cabinet built-in), I will have at least a 15 foot run of speaker cable to reach the right speaker.

I have a decision to make on whether I should invest in a long run of interconnect OR speaker cable.

Thoughts?

Almarg is correct. And you should have no difficulty finding 15' runs of interconnects - there are almost always a lot of used long interconnects available at any given time on Audiogon (and they're usually cheaper than speaker cables, which use a lot more conductor).
Some cables such as OCOS are designed to be used in long runs. I use 5.5m lengh with no problems.
All things being equal, it is MUCH better to have your high-level signal (Speaker wires) runs longer than your low level signal (Interconnect). It is not an opinion, it is simple physics.
Simple physics? Since when has cabling physics been simple? For that matter, when have all things been equal either?
