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

... I really didn’t sign on to audio Gon tonight looking for a beef. I guess some of you guys are hearing something, I tried to hear it and spent a bunch of money in the process and nothing...

Money that may have been better spent on things that do make a difference

My answer is yes to your first question, but your own conclusion is incorrect. It doesn’t require a detailed knowledge of logical and/or formal fallacies to understand why that may be so.

…

People often will spend a few hundred or more on questionable things, and do it multiple times. And often not spend teh same total amount in a single “upgrade”.
Hope rings eternal.

@atmasphere do you have experience with your amps benefiting from using the two example of power conditioning units that you mentioned?

@hilde45 +1.  And, thank you.

On my system power cables do make a difference with power conditioner or similar such devices. I use two WyWires Juice II Platinum HC power cables on my Nordost  QB4, one feeding the QB4 and off from that one feeding my amp. It clearly is noticeable changing out power cables. I’m evaluating at the moment a Nordost Valhalla II PC feeding my PS Audio P10 and it is noticeably different than the WyWires Juice II Silver HC I own and currently use. Dedicated circuits definitely make a difference as well, but system dependent. Before dedicated circuits my Pass X250 was a little on the lean side and lacked authority; adding dedicated circuits opened up the Pass and extended and controlled the bottom end. I ran No.10 to my amp and another No.12 circuit to the rest of my system. Best just to try for yourself and not be steered one way or another by others.

@raysmtb1 Pretty sure guys paying $37k for a cable are not going to drive a $37k car.  

@atmasphere great discussion of these two power conditioners.  I wonder 2 things: 

1.  How much load do they add?  To supply a 400W amp does the load (and heat in the room) go up to 800 watts?

2.  Are these expensive high end units able to totally eliminate transformer hum?

thanks,

I guess all the "me too" posts makes it official:
they don't know what they're talking about.

All the best,

Isn't it curious how one side says:  I hear things 👍🏼 and the other side calls those people stupid.
