I'm not trying to start a heated discussion on cables, I'm just trying to ask an honest "i don't know why" question because I'm not educated/trained in electronics. At least not to the level of understanding the theory/principles behind it in audio systems. Repair, replace and troubleshoot? I'm not too bad at that. Theory/principles? Pretty sketchy there....I'm more technician than engineer when it comes to electronic stuff.
Why do RCA interconnect cables all seem to be somewhat of a coax construction and not a simple 2 wire type?
I get that line levels are low strength signal and the shielding of an outer braid helps reject external "noise" sources like RF and EMI, but is it really that much of a problem if a simple two wire cord is used? Would they really be at risk of picking up RF/EMI in a home audio scenario?
I have cut open a set of the really cheapo rca cable before and they are even core and shield type construction, even if they are very (very) thin wires.
There must be a good reason for it because the cheapies would be even cheaper (IE: to construct) if they were simple two wire cords.
Again, not trying to start something, I honestly just want to understand the "why" of it.....
