Would like to share my just finished experiment with speaker wire bought from Raon. My observation: For each size increase, the copper strand double in thickness.
1.) Gauge #16 - Where I started.
2.) Gauge #14 - Clarity become apparent in all ranges.
3.) Gauge #12 - This is the maximum size for clip type terminal. Low mids and bass increases. 25 pesos/meter
4.) Gauge #10 - This one is the chord type. The punch from the bass were too sharp and strong that it drown out the clarity on other frequency. 150 pesos/meter
My verdict: Don't have to go beyond gauge #12 for a standard set up.
bear in mind also that different users will have different observations....
you may want to try battery cables, in the welcome rotonda setup i visited,
those were used as speaker cables for an ASL 845 SE power amp...
i look at speaker wires bought from raon with some skepticism...napaso na ako...
but then it is just me, surely others will have different experience...
i use cables purchased from automotive supply shops....
if you must buy from raon, i suggest you get those cables with black and blue cores,
these are instrumentation type cables, double insulated, #18...
i will stay away from those cables with transparent plastic insulation,
the copper cores are brittle....
