A best-seller primarily because of its non-sacrificial protection technology, which allows it to withstand and "reset" after major power surges rather than wearing out like standard surge protectors. It offers 70% more filtration than the Australian industry standard, utilizing "Dynamic Active Tracking" to clean electrical noise on both the upward and downward curves of a power sine wave. Reviewers at The Audio Tailor noted immediate improvements in clarity, dynamics, and soundstage depth when using the P8 with high-end hi-fi systems.
