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?

Simple physics? Since when has cabling physics been simple? For that matter, when have all things been equal either?
4est: cable's speaker or interconnect is a simple science.Its the cable manufactures that turned it into alchemy.A very famous cable supplier of high end cable admits that there is no truth to cable direction coding. And the only reason the arrows are placed on cable is that there is a high demand for it.
i have tg audios that sound terrible when you reverse the direction.

they are my favorite speaker cables otherwise.

i think there are a lot more variables to these things than can be put into sound bites.
I received this email response from a dealer:

Interconnect cables can be either RCA single-ended style or XLR balanced types. The XLR balanced type reduce the noise character and have negligible signal degradation over length. So these would be the preferred cable whenever possible regardless of length, when connecting source components, preamps and amplifiers.

RCA single-ended types are prone to noise pick-up whether from electromagnetic interference or from radio frequency interference and will have high frequency degradation once over 6 feet in length. If you have no choice but to use this style, keep the lengths closer to 3 feet if at all possible.

The least signal degradation will be associated with speaker cables since these are carrying a higher power signal where effects of resistance, capacitance and inductance are easily overcome with the stronger signal. If there is a choice between longer interconnects versus speaker cables. choose the longer speaker cables for better results.
