Same here I'm active in IT now but was originally educated to become an electrical engineer. In my system topic I've detailed all the things I've tried that a few years back would sound utterly crazy but many did work. Keeping an open mind ("a mind is a terrible thing to close") and trying things for yourself really IMHO really is the best if you're on a hunt for ultimate SQ. Enjoy!
