I don't think you'd notice much from the monsters. $100 cables are only going to improve the quality of a system that is proportionately expensive.. So if you haven't spent over a grand on your speakers, I don't think you'd find much of a difference with monsters.
And I know it's a bummer, I have horrible technology luck. Tons of shit I buy just arrives defective. Or they send me the wrong thing. It's really weird. And sucky.
