Bayliner - Can you hear the difference between red beans and black beans?
Questionable Tweak
Someone on Audiogon mentioned using an air purifier to improve the sound of their system. I dragged my wife's purifier into my listening area, cranked it up, and.......,no change at all. They said it removes dust particles,to improve the sound. Has anyone ever heard of this?Is there any science to back this up?
