Do speaker cables really make a difference ?

Have just upgraded from Morrow Audio SP6 to SP7.  And once again, the better the cable, the better the sound of my system.  Specifically, better resolution and imaging, and perhaps a tad more bass now that they are breaking in somewhat...it's obvious to me that one can get very carried away w/the amount of money invested in I/Cs and SCs; the prices of some exceed the total $ that I've put into my entire system...but the caliber of your components should determine where this "law of diminishing returns" kicks in..I'm not there.

JB52, get help, man!

I just upgraded my speaker and interconnect cables to the Neotech Sahara rectangular OCC from harmonic Tech round OCC what a difference as good as around OCC is the rectangular OCC is even better, not cheap but well worth it.

if you can hear the difference, they do

OK assuing all the wires attached to the components are top shelf(and likely costly)and the synergy is perfect. What happens to the sound(signals) when the signals  meet the cheap zip cord like internal speaker wires?  It can't be good can it, How can it be good?

1 - the internal wiring of speakers is not as important, because (a) they are very, very short runs, way shorter than the speaker cables, and (b) they are inside the cabinets (not subjected to other environmental factors associates with the speaker wire going from the amp to the speakers).

2 - Good speakers use good internal wire, and not crap / zip cords.

Hopefully I did not waste my time writing this, as I smell a snarky question, like you folks always do. Oh well...
