Well said Alan. In fact I have read where power conditioners can adversely affect the sound, as in deteriorating the signal strength. I use APC battery backups for my DTV, RPTV and computers. However I do hate the MOVs that come in these fancy (monster & panamax) so called power/surge protectors as well as the 10$ strips. I had an MOV catch fire in an APC and nearly burnt down my home not to mention, in real world use you need to replace these MOVs (Metal Oxide Varistors) every couple of years, meaning purchasing a new unit, MOVs are not user replaceable. I bet ya the salesman didn’t mention that. As a result I learned a lot of things about MOVs and they are useless. Once you learn how MOVs work, you’ll wonder why you ever bought one and whos bright idea it was to use them, they are outdated. I only use series mode surge protection found in the
Brick Wall series There are also other Series Mode units such as
ZeroSurge and
SurgeX
As an example, I live in Miami Florida and when Wilma went through, a cat3, she took down many transformers and when our transformer blew it went out in a flash of glory. As a result my neighbors stove, tv, vcrs, computer, water heater, you name it, she lost it. Even things she had plugged into power strips and her computer which was plugged into an APC, fried! I had every major appliance unplugged or breaker thrown off except the refrigerator and tv. I took one of my Brick Walls and used it for the spare tv and refrigerator. When the power went I thought it was all over, I’ve never seen a transformer blow like this one did, it was quite a show. After the hurricane passed, I fired up our generator and walla, the refrigerator and tv still work
I think that’s the best testament to which is better, Series Mode or MOV.
Here’s a quote from the Brickwall site:
MOV’s function by creating a short circuit (usually to the neutral and the ground) when a preset voltage threshold is exceeded. Essentially they divert surge current away from what the surge protector is protecting. Unfortunately MOV’s are sacrificial components. This means that the performance life of any surge protector utilizing this technology is finite. With every surge current diversion above a modest level an MOV comes closer to its inevitable end.
And a nice explanation of how MOVs work from a third party:
