I'm having a really hard time with: "Power cable reduced my soundstage"...
A shielded power cord would have zero effect on taming a lightning surge. Truthfully, the lightning surge was mitigated by the sacrificial action of MOVs in the power conditioner. The damage that took out the Krell and its power cord also damaged house wiring and related components (panel, sub panel, receptacles, wiring, etc, etc,) and that means rip and replace all of that too. You should hire the services of a reputable certified electrical contractor to assess the damage to your home’s electrical system, and get in touch with your homeowners insurance provider ASAP. |
Hey @sleepwalker65 : Truthfully, the lightning surge was mitigated by the sacrificial action of MOVs in the power conditioner. The Furman Elite does not use MOV's for electrical surge protection (but may for coax, not sure). It is of a class called "series mode surge protectors." You can read a little more about those here: https://inatinear.blogspot.com/2019/04/power-management-for-frugal-audiophiles.html Lightning strikes cause damage in large part from an EMP pulse they generate, you can read more about that here: https://www.edn.com/electronics-blogs/brians-brain/4435969/Lightning-strike-becomes-EMP-weapon- So, that's why I'm wondering. Hey @tom8899 - Was the power cabled due to the surge, or was this a mechanical problem? |
Shielding, when done properly, can be effective. I say “properly” because most unbalanced audio cables use the shield as a signal-bearing conductor. Exactly, and noise, as well as surges, can be induced from/to the power cables directly. An EMP pulse from lightning doesn't have to travel through the power company's wiring the power line to damage equipment. Best, E |
