Thanks all.
@holmz I don't necessarily have a problem. Don't know if I have a problem or the equipment to test if I do. Was more a general question after viewing reviews of DC blocker products and the positive affect for minimal investment.
DC blockers - what's your experience
Just viewed a video about the AudioLab DC blocker. Then watched Paul from PS Audio explain how it works and now I’m intrigued. Anyone with insite?.
