Why do I need power management if I have a great power cord?


Isn't it kind of unnecessary to additionally add a power conditioner if I have an expensive audio file grade Power cord connected to a component?

So you buy a Power conditioner from a hi-fi store and they say oh, you need a really good power cord to go with that and then another one to go from conditioner to the component. Do you need it all and why? Seems the last couple of feet before the component should be more than enough.

I just saw your questions. I’ve spent thousands and thousands of dollars on all of this junk and it didn’t make a difference to me or any of my friends that I had over two here for themselves. All of my componentry is Macintosh it all has the stock power cords and all of my inner K’NEX are from Best Buy or Amazon. I have no noise in my system whatsoever. There’s no need for any of that redundancy

@raysmtb1 Thanks. So there's you, your friends plus I guess others with your conclusions. Then there are thousands who testify to a difference. Shall we call it a draw and agree that it's important for people to test it out for themselves? You did that and have reached a justified conclusion...for your ears, setup, etc.

Sorry, you are conflating issues. First of all, yes, you are right, one of the major improvements in components is how it address power. This is one of the keys to great sounding components… correct. But the more the more better. For instance, I added a $9,000 power supply to a $9,000 DAC (Sim Moon. 650D adding the 820 dedicated power supply)… big difference. This is why flagship components are frequently two box components, with one remote box dedicated to just the power supply. 

 

A really good power conditioner, and direct lines I have put in have significantly improved my sound quality above that.

 

A power amp has different requirements. It needs unconstricted current or it is going to loose dynamics. So, most of us with high end systems use a direct line to the amplifier with no power conditioner and use a power conditioner for our other components… lowering the noise floor… by the way, something you do not hear directly. It takes experience to understand what a noise floor “sounds like”… you don’t hear it. It is the blackness in the background.. the comforting silence that makes you relax and fall into the comfort of nothing.
