Makeup brushes for Christmas

My wife gets me! I opened up one of the gifts from my wife and wadddya know, makeup brushes for cleaning my stereo gear! She had observed my OCD tendencies for years, carefully brushing off each little button with her old discarded brushes ( after I sterilized them of course) and decided to get me a set. I've seen posts about the compressed air, but there's something more intimate about the brushes for me, I swear my babies sound better after a gentle brushing/cleaning? Please tell me I'm not alone!
