TechRadar's verdict

"We’ve heard bigger leaps in performance from other mains filters, but they all cost considerably more than this one. Even with ‘standard’ mains leads, this is a worthwhile addition to a decent hi-fi set-up"
  • Well made
  • Offers a clear improvement in clarity of sound to a range of components
  • Prevents cross-contamination between units connected to it
  • Lacks the switching features of more expensive products
  • Does little for power amps
