AudioQuest PowerQuest 3 Surge Protector 8 Outlets & 4 USB Charging Ports

I bought it for my Sony A90j TV. The TV has rich and vibrant colors. But there was still some background noise that caused watching fatigue. The PQ3 has two outlets dedicated to 4k/8k video display and I used one only. The fatigue-causing irritation disappeared immediately. I became curious and wanted to find more. First to my notice was the shades of color being richer and subtler. The blending of colors in adjacent areas was smoother, either at low or high brightness. Next, the color seemed to be a bit more transparent, causing an increase in depth of the objects in display. The improvement was also made in sound quality. The internal speaker array sounded darker and fuller. The digital output from the TV was improved, too.

There are MUCH more expensive line-conditioners that I'm sure sound even better but these created the darkest quietest background I've heard from other line-conditioners of the same price. I have used MANY Monster Power Line-Conditioners in the past, including the Monster Power Pro 2000, which had either dual- or triple-stage noise-filteration and was $300-$400 new. The only issues I have with them (I say "them" because I bought two "3's" and three "2's") is that they are mainly constructed out of plastic (my Monters were of mostly of metal construction) and only have 7 or 8 outlets (my Monsters of similar pricing tended to have 12-14). Plenty for simpler more modern systems but my home theater uses many separate components and I also continue to use a vintage $1,300 Laserdisc Player and a very high-end at the time $500 Super-VHS VCR. (Yes the picture quality is lacking but I have many obscure unreplaceable VHS tapes and, until Blu-Ray, the sound of the Laserdisc is FAR Superior to compressed movie audiotracks.).

Excellent item, performs as expected
