Am convinced this pricey German box is doing absolutely NOTHING to filter noise or regulate voltage. Voltage still noticeably fluctuates with guitar amps to a desk fan .There is NO voltage output readout to verify this though....gee wonder why? The EMI 'LIFT' filtering feature is a %100 JOKE. Using an AUDIOPRISM NOISE SNIFFER I receive radio stations through my wall outlets and still do through this $725 poorer. Not happy with this thing. Waste of money. Feel like I got screwed, oh well.

If you know what you're buying and what features are practical and not gimmicks, also if not full new price, great deal. If it doesn't have automatic voltage regulation, not worth price ,that's number one feature most important for sensitive electronics! Especially with aging power grids, and areas with power fluctuations. I noticed on West coast in summer it corrects voltage alot to keep ideal 120 though it generally keeps it between 115 to 125. Brownouts and surges or high voltage damages internal components causing failure sooner. I've never lost any electronic devices, all like new for last 25 years! I've always used A power conditioner with AVR. I still own 2 original like new ps3 fats 60-80 GB backwards ,plasma TVs ,one 12 years old no burn in like new. I give credit to these units!Read full review
