Hope, I'm not slipping into some mild paranoia. I've recently bought a Kemp SR and can't say it appeared to do much, sonically. However, I've kept it plugged in since I thought it might change over time and, anyway, can't harm. Reading Fork's comment, however, I suddenly realized I have had problems with dry eyes (but then again, not all the time), also my head sometimes felt as if it was caught in a bench vise and occasionaly, a whistling noise entered my ears (but then again, I've had that e.g. on trains or planes). But you know how it is once you start paying attention to that sort of thing, it gets worse. So I've unplugged the SR, try to evaluate what happens over the next weeks.
Apart from that, Ozzy and Fork, have you noticed a difference depending on how you placed the SR's antenna (height, orientation)?
