I use a couple to. I also degaussing my ES Sonys. Anything with a physical hard drive you have to be careful, you'll wipe the drive.. If you open up almost anything that has spinning or moving parts with unlike metals, some become magnetized. There is only one way to fix it.. Degaussing. Same with all stereo equipment. How often is it done. NEVER.. I have R2R, Turntables, and silver disk, I degauss them all.
Please don't degauss a Server and if you do, would you please take a video and post it.. Thanks
Merry Christmas..
