I tried big-box-store audiophile cables but the sound from my JBLs turned green. I much preferred the blue sound I get from standard duplex copper cables. I've also seen a tinge of purple when I tried the Opus MM plus the room had just a nuance of a baking-with-vanilla smell. I eventually figured out that if I used 18-gauge copper on the (+) terminal and Alan Share Modena on the (-) that the sound was a nice robin's egg blue and the room smelled of Dr Pepper Jelly Bellies——and that made me very happy.
But then one of my daughters is a synesthete.
Whatever blows your skirt up, as we say around here!
