Tweek Geek’s Bybee Stealth Power Purifier popped onto my radar via Sablon Audio’s Mark Coles whose power and audio cables have greatly impressed me. A short email exchange later and a Stealth Power Purifier was on its way north to the land of snow. As I have stated in previous reviews, PLCs have been a bit of a hit ‘n’ miss for me. Whilst I usually do hear improvements in sound quality and musicality (not always the same thing), I generally don’t pine for them when they leave unlike, say a loudspeaker or amp.


Furthermore, I don’t believe I’ve ever come across one that made nice with my Audiomat valve amp. Either dynamics constricted; or tonal balance shifted out of whack. Where many see powerline conditioning as a crucial component to their systems, I’m a little reluctant to go that far.

Maybe I live in an area blessedly free of severe mains pollution? Or perhaps the power supplies of most of my components are a tad more robust than others? O so I thought.
