My name is Scott Campbell and over the last 30+ years as an avid audiophile I’ve tested and listened to just about every conceivable passive potentiometer (volume control) including Bournes, Alps Blue Velvet, Alps Black Beauty, Penny and Giles, Dact Switched resistors, and transformer (TVC) based volume control.
I’ve also owned and reviewed some of the most famous and expensive valve, solid state and hybrid preamplifiers available.

In my opinion, the Lightspeed Attenuator has bested them all in every listening test I could devise.
