Customer Reviews (4.6 / 5 · 5 reviews)

Mia Z. ★★★★★

Plugged my turntable and phono preamp into the high-current outlets and the background hiss I'd just accepted for years is basically gone. The eight outlets are laid out with enough space that my chunky power bricks don't block each other.

Daniel ★★★★★

Swapped my old strip for this and the background hiss through my speakers basically vanished. Having separate high-current outlets for the amp makes a real difference on bass-heavy tracks. Eight outlets is more than I need, but I'm not complaining.

Harper U. ★★★★★

Plugged my 4K player and receiver into the Linear Filter outlets and the picture looks noticeably cleaner, less of that faint graze in dark scenes. The two high-current outlets handled my amp without any hum. Eight outlets filled up fast, but that's my rack's fault, not the unit's.
