Science starts by first learning what already exists. 120 AC volts is first filtered. Then converted to high voltage DC. Then filtered again. Then converted to well over 300 volt radio frequency spikes.
Does not matter how clean that AC power is. Power is now 'dirtiest'. Then superior regulators, filters, and galvanic isolation converts that 'dirtiest' power into rock stable, low DC voltage.
Most who recommend power conditioners and other gobbelty gook have no idea what already exists. Then assume some magic box might make sound cleaner or tinny. Useful answer starts by learning what already exists - and numbers.
Tie a knot in a power cord. That is also a power conditioner. Then add numbers. It does near zero power conditioning. Many power conditioners are little more than wire knots selling for big bucks. The scam works.
Does not matter if that conditioner eliminates high frequency noise. Power supply first makes well over 300 volt radio frequency spikes - worst noise. Worst high frequency noise is only solved by superior filters, regulators, and galvanic isolation that must already exist.
One says all UPSes have surge protection. He is correct. Destructive surges can be hundreds of thousands of joules. UPS only contains hundreds of joules. To be any smaller, it would be zero joules. But since it has near zero joules, then most claim it does 100% protection. Recommendations not tempered by numbers and other relevant facts (ie common mode, a low impedance connection to earth ground, etc) is best ignored as hearsay, wild speculation, or knowledge from advertising. That is what so many 'experts' use - junk science reasoning and no spec numbers.
