No. Humidity is not really an issue unless it becomes extreme. Here in Florida with the house always closed and the AC system always set to dehumidify we are lucky to get under 60% RH. I see the same concern on camera forums where people are buying dry cabinets just because they bought a new camera and are new to the hobby. Same for stereo stuff. I'm still using gear from the 1980s as are most of my friends who are into audio. Just not an issue unless you are above about 75% regularly and that also becomes an issue for structures :-)
