Dry brushing a record before play is very important for both stylus and record longevity, not to mention getting a quiet play. This video shows and demonstrates 9 different brushes, plus a device called the Spindle Spinner that's used to manually wetclean records with relative ease while protecting the label from getting wet. A more detailed write up will be on the analogPlanet website. NOTE: the AudioQuest carbon fiber brush says in tiny embossed letters to hold by the gold part to take advantage of its antistatic capabilities. Sorry I didn't see that when I did the demo. It works much better if you do! Also the BLACKAUDIO BRUSH is meant only for wet cleaning and it really shouldn't have been made part of this demo.
