Except each designer uses different level of implementation and quality. Some amps have poor filtering, some don't. You don't know how good your amp is at filtering EMI without trying a high quality power conditioner. If it makes a difference, then clearly your amp isn't quite as well designed as you thought. If the difference is inaudible, then it's a well designed amp. Also EMC standard differ depending on the product class. The standards are not designed around what humans can perceive, but what allows a product to work without fault and/or preventing said product from interfering with others. As long as X amp still works without any faults and/or it doesn't interfere with other electronics enough to cause them to have a fault - it's a pass. This is the bare minimum for EMC mitigation. Power conditioners aim to improve this beyond the bare minimum legal requirements, to the point where said product is performing at maximum performance.

@@campersruincod6134 I build and design my own amplifiers. Common mode choke\capacitor arrangements lack inductance and sufficient capacitance to block RF and lower frequency interference. I produce my own music, so interference is especially important. I usually have common mode chokes tuned at 1Khz, in addition to RF in series: low cost. Interference is particular issue with PWR converters, since sine wave is synthesised from switch mode, RF appearing at output. I still think snake oil is going on but assuming funds not an issue, it's harmless.

@@hoofbags it's definitely not snake oil so as long as it's an actually good power conditioner, say like a Furman Elite or Reference. Is it diminishing returns level of performance gain? Yes. You will hear larger difference from upgrading other parts of your system. It's more for people wanting to optimise the last bit of their system to maximise performance.

well said!!

Can you read ?

@@MrSummitville don't be a prick

@@milesfantastic Don't be a lazy asshole ... READ !

I think it has to do with weather we pay for music or get it free. Junk in junk out. Remastered doesn't mean anything I/you can put our version out there & call it Remastered. also how old the capacitors in our amplifiers are will cause it to constantly sound different

@jackofalldaves agreed.

Precisely. What's the point? The point of most hifi... SELL!!!!

I love my hair conditionner, it makes my hair smooth without cancelling the dynamics. It is Pantene Pro-V but the one with snake oil.

dean setiono - looks like a brand new

and none of these reviewers has been able to illustrate the difference in sound quality using a conditioner so from my point of view the reviewers are the trolls.

You want them to illustrate the difference via a KZfaq video? Wow.

Barry Rodgers - there is a major difference. These guys squeeze the snake extra hard

The difference? For one you pay extra!

It's not difficult. Simple engineering really. Even if they both uses the same components, more filtration = increased reduction of EMI. Could go from 20dB reduction to 40dB reduction within a system depending on the components. Lower is better. Simple as that.
