Power cord choice?


Hoping to change (or upgrade) my current PC in use with my ARC CD3 Mk2. Currently I'm using a Locus Designs Polestar and setting a limit $600 max. I'd like to find a cord that can get more micro details from the ARC yet, I'd like to retain the smoothness but, try to open the sound stage and get a little more bottom in doing so. I listen to Alt rock (Sir Sly, The Killers, Gargage), rock, blues using Classe CAP 151 integrated and Apogee Slant 6s. I know this is subjective but, I'm also doing my best to work with my budget constraints and I'm not going to change if the improvement would just be slightly incremental. I'd like suggestions to consider, please.

That makes a lot of sense. 15A inlets, esp with the female connectors having that notch in it, makes for a swiveling connection. I was advised, and will do it soon, to wrap the connection in Teflon tape to tighten the fit. 

Funny you should mention, I tried a swiveling connection with my female and had the same problem with it sliding out. Tried Kegel. Never thought to try Teflon.  
I guess I am the moron now. I’d rather trust you guys over Armirm at Audio science Review. He’s not that accomplished of a guy, I looked him up, He probably bought that $28,000 piece of review equipment off of the interest he made on his money this month after retiring from Microsoft. He’s probably bored so he decided to start a website. Here is his story.

I am Electrical Engineer by degree (and hobby) although most of my professional experience has been in software development. After 35 years in technology sector, I retired as VP of Digital Media at Microsoft in 2008. I am founder of Madrona Digital which is a company that specializes in mid to high-end electronics for residential and commercial properties. I also advise local companies in digital media and co-founded a company in that domain that was sold a few years ago.

Hey Polly and vinyl shadow why don’t you post your chops up here and let’s see who the group would rather follow.
Was talking with Max Townshend the other day. Long rambling talk from one fascinating subject to another. At some point he mentioned I should check out this Audio Science Review, the founder is right here in Seattle.    

So I go check it out. WTF? Not one even slightly interesting subject. Would not have thought this even possible. Eventually I decide to bite the bullet, try and read this one post that was pinned and seemed to be sort of a statement of what the site is all about.   

WTF?! They apparently are all about justifying a certain level of expense, but no more, and you are a fool to pay more than whatever that level is, according to their mandarins, as determined by their own arcane semi-mystical set of measurements.   

It was at this point I knew Max Townshend is a prankster with a wry and very witty sense of humor.  
I don’t know Max but after seeing his videos which are very science-based I would guess that he would agree with the audio science review. Most scientists know how to speak the same language. Maybe all of you guys should meet on Bob carvers boat and talk about science and measurements and cables. If those three Guys would say that cables made a difference then I would believe it.
