Very High quality, Specially made variable resistors
The thick cable cores allow for Very low resistance, and maximum, audio throughput.
The Trimpots (The variable resistor wheels/ adjustment knobs) are SPECIALLY printed and manufactured for this cable to come with Very Low resistance at the highest volume setting.
Combined total audio output loss is LESS than Half a Decibel at 80dB!
- That's better than many audio extension cables !!
You should could just try it and see if it works for you...
