Noise Destroyer


Excerpt on the HFT Noise Destroyer from a broader review on 6moons.com.

"Which brings us to the Noise Killer, a parallel filter said to shunt HF distortion in the AC wiring without dulling dynamics. HiFi Tuning recommends that the first filter be installed directly at your electrical panel where the majority of distortions will be handily addressed. Subsequent filters may not be necessary, otherwise additional ones can be employed on an outlet multiplier or adjacent to a noise source.

To identify such sources, HiFi Tuning developed the Noise Detector, a gizmo which modulates the noise to make it audible as hum or surf. Once a noise fiend is pinned, there are two solutions: Out of the chain or, in parallel, in with the killer. This is so effective that I cried foul at first: Detector into the outlet multiplier, gain cranked - terrible noise. Killer inserted, silence. "No way," thought I. This game had to be rigged like a bad Carnival stand.

Was I in for a surprise when I removed the filter to search for dirty culprits. I honed in on a light dimmer but the noise persisted. The printer? Bingo. The noise diminished to not completely eliminated but a lot lower. Now I heard voices though. Radio voices. Seems my AC wiring doubles neatly as a radio antenna. The return of the killer meant a return to silence. (Sadly, the detector is not commercially available, merely on loan to dealers to optimize installations.)

What does the little black box sound like? It doesn't, at least not in a dynamically detrimental way. Dynamics are as they were before, no less, no more. But something's up: The background is calmer and blacker, enhancing the contrast of individual sounds. There's less grating, less nervousness on strings, less outline blur on instruments. Sounds become more dimensionally tactile. Beyond improved 3D-ness, the depth perception increases and virtual space grows backwards.

Needless to say, the exact effect and degree will vary with AC and system. My colleague Jörg didn't experience improved depth but his more tacit dimensionality was similar to mine, with sounds better differentiated, less clumped together. Again: borrow, experiment - and buy, perhaps. As for me, these are keepers."
