The Yaqin factory power cord is junk which is a shame since the build quality of the buffer itself is surprisingly beefy. Very thin, I wouldn't trust it to charge my toothbrush.
"And that also goes for speaker wire.Multi million dollar live video and audio trucks just use regular old belden 16ga speaker wire and what ever power cord is acceptable for amp draw on the really expensive equipment."
I'm closing down RC Cables, Natoe convinced me...lol.
