I got a nice Parasound A23 amp and P3 preamp pair from this site. As soon as last winter arrived, one modest static touch blew out the pre, to the tune of a $300 repair. I tried to be careful afterwards to discharge before I touched it. But, alas, first cold day this winter I transmitted a static charge so small I could barely feel it, and poof! flashing lights, preamp dead again. I've had it now, and rather than repair, I would like to replace the preamp with a different brand/type that isn't so susceptible to static electricity damage. All advice welcome.
