The $250 power cables and $600 power strip that dethroned my $10k Shunyata Everest

@westcoastaudiophile Physics to the rescue. 50A x 120V = 6000 Watts. I suppose you are in US where 120V is norm. Did you blow your fuse?
Let’s consider you are correct and you have abnormally strong fuses and abnormally thick wires inside your walls.
Let’s take 10-gauge wire then. It will cost you only several $ more and no fancy gimmicks. 
The voltage drop per 10-foot wire will be less than 1 Volt at 120 V and 50 Amps. Again, I am talking about continuous load which is much more strenuous compared to a variable load.

My final point in this conversation - you mentioned "good quality interconnects". They are all good quality. They are all UL (Underwriters Laboratories) certified, meaning they intend to do the load job properly. Otherwise they are illegal for use.
If, by any chance, your "interconnects" are not good, you are simply risking a fire in the house.

I am not trying to convince anybody. Only promoting a scientific point of view. A lot of people considered that quite helpful.

Have a great sound!

@ionna22 Have you noticed that this westcoastaudiophile guy can't even manipulate the edit functions on this site. It's been decades that a person can do anything in the Tech, science or business world without basic computer skills and he wants us to believe he's the least bit creditable? For instance, he's just copying and pasting statements and placing quotes around them and when pressed on his claims such as the one I quoted below, you blow him completely out of the water!

@westcoastaudiophile "I’ve measured (scope) up to ~50A peak incoming current short time spikes in 400W amp."

You're response -

"Physics to the rescue. 50A x 120V = 6000 Watts"

As a lay person and experienced hobbyist, I'd trust your response!

It was briefly mentioned before but I thought it would further add to the context of this thread.  Beyond Roper and my feedback, Mark Coles, the owner of Sablon Audio, posted on WBF.  I do have a QSA-treated Sablon Audio Ethernet Cable in my system.  Mark has an excellent reputation for building high-quality cables and cords.  It is worth reading his comments and his partnership with QSA Lanedri.  
In essence, he took a very good cable that he built, gave it to QSA Lanedri, and, in his words, improved the overall SQ.  Should that account for anything?  Well, it is not a $5 cord selling for $250, but it is the same concept.  The sound of his cable improved after being treated. 

@ionna22 @faustuss 

@westcoastaudiophile is correct. 50A transients in a 400wpc amp without soft start circuitry seems pretty normal.

The duration is in the milliseconds though, so nothing has time to overheat and no fuses blow.

Available short-circuit current (ASCC) is the measure of how much current a branch circuit can deliver through the breaker during a bolted fault condition (aka a dead short). For 14AWG wire it is if I’m not mistaken >500A.

This thread is very amusing.
