Here's the thing. What are the possible sources of noise you are trying to clean up? If you live in an urban area or near any commercial or industrial facilities, you're likely to need some cleanup. If the circuit to which you power your system is shared with appliances, dimmers, florescent lights, etc., you're gonna need conditioning. If your system is composed of mid-level components that don't properly shield the noise they generate internally, you'll need help. Finally, if your speakers are high sensitivity speakers, you'll likely hear some of the noise. BUT.....If you don't have any of the above issues, and can't hear any noise in the black parts of music, you'll likely be wasting money and possibly adding problems by adding conditioners or regenerators. Don't believe the hype about improvements on problems you don't have.
