Hi all. Does anyone know the AWG of the stock power cord of the amp Ultra?
I am thinking of upgrading the power cord to an Audioquest NRG X3. But the AQ is "only" 16 AWG.
I would not want to go smaller than the stock power cord.

Now that I am home, I turned on my phone light and looked over the stock power cord. It is 18 AWG. IF I decide to buy the Audioquest, the conductors are twice as large as the stock cable, so ok to use.
 
A 3 foot stranded 18 gauge power cord has a resistance of 0.019 ohms. A 16 gauge cord is at 0.012 ohms. So both have a resistance of under two hundredths of an ohm. A 15 amp wall socket can deliver up to 1,800 watts of power, so a rough back-of-the-envelope calculation says that the 18 gauge cable will use about 3 watts leaving 1,797 watts for the Amp Ultra while a 16 gauge cable would leave 1,798 watts available to run it. I'm in the camp that I wouldn't waste the money for a new cable. That said, I recognize that some audiophiles firmly believe they can hear profound improvements when they switch power cords. If you are one of those, have at it and enjoy!
 
if you want to hear a difference, you will hear a difference..
I agree there is some form of confirmation bias in these matters. I would not pay megabucks for a power cord like some do.
The AQ is "reasonably" priced for such a product.

FYI, Shunyata Research also providing c5 plug power cord at similar price, which is called “Venom V14 C5”.

Thank you. I thought of Shunyata. But, my dealer no longer sells their stuff. I decided to go with the AQ. I should get it within a week maybe two.

Congrats on flushing over $100 straight down the toilet. What’s terrible is your dealer knows it’s a scam, but it’s a scam that pays their bills so they’re fine with it.

I feel bad for WiiM engineers. Can you imagine the lengths they went to design the Amp Ultra to a pricepoint — all the constraints and compromises that meant for internal components that actually matter, and the talent they used to get it all to work so well — just to watch customers turn around and spend 25% of the total price on the most meaningless part swap possible?

Congrats on being a douchebag. Go back to "Audio science review" and fondle Amir's bits some more...
 
Maybe I now only feel half as sorry as I did :ROFLMAO:
No worries, just trying to remind everyone in what was meant to be a reasonably light hearted way of the first forum rule:
Be kind and courteous.

Not quite as poetic as Bill and Ted, but close enough.
