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.

I have shared in a curiosity occasionally about the impact of a Cable on Device, be it a Interconnect, COAX, Speaker Cable or Power Cable.

I am not too concerned in the early stages of an investigation about a Cables Construction Design.
I am interested in experiencing a Wire that is used as a part of the Cables Construction.

To date I have used various Wires in Various Gauges  in Power Cables across many years.
As most of my interest in my system is now about generating the most satisfactory interfaces, I am spending a larger proportion of time gathering a further knowledge about cables, i.e, Wire, Construction and Termination. 
 
From past and present experiences, my assessments have led myself to believe that a particular Wire Type can impact on the SQ and the affect a  wire can have on a device is varying.

In my trials with Power Cables I have used standard copper, and OFC, and recently brought in PC Triple C. ( Copper, OFC, OCC Copper and Silver, and PC Triple C and D.U.C.C) have all been trialled as either a Interconnect, COAX and Speaker Cable.
This experience merely means I understand how certain Wires at a given Gauge are interfacing within my system only. 
   
My usual formula for a Trial, is to purchase a used Cable, ( the reason for buying used, is that it will hopefully have quite a few hours of usage behind it ).
I commence with using one Power Cable only and use it on different devices, and allow it to be in use for quite a few sessions before I revert back to a previously used Cable.

Bearing in mind I don't undertake the Power Cable experiences as a regular practice, when I introduced PC Triple C to the System, I was blown away.
When a attached to a CDT it was a enormous impact for the better, the qualities remained but it was like the improvement on the qualities jumped to a better place, and the Soundstage become much more Voluminous, like a few extra pumps were added to the balloon.
Ditto, when the Power Cable was added to the DAC.
Almost Ditto, when the Power Cable was added to the Phonostage.

I have not started on the Mono Blocks yet and the Internally terminated Pre Amp will probably get treated last with a exchange Cable. 
I am now looking to bring additional Power Cables on board, as it seems there is so much to be on offer, if the CDT and DAC both have the same Wire in the Power Cable. 

There is no recollection from my trial experiences throughout my whole history of building a System, where a use of a Wire has impacted on the System in the noticeable manner these modern design wires are capable of producing, at any interface.
The perception created where there is more of everything, a furthering of the insight, the added Volume to the Soundstage and improved cohesion across all frequencies is a Joy to experience.

The impact a Solid Core Speaker Cable has had, has now got myself all fired up to exchange the Xover to Driver wires within the cabinet, I want more of this X Factor.
My previously used Speaker Cables were used in a demonstration/Bake Off with Speaker Cables,  where the combined Value was approx'  £7000.
My Cables were selected to be used in the Final Comparison between two Cables.  I did not see these ever requiring to be exchanged.
I have yet to reinstate my previously used cables, as the New Wire is New and I am looking to let it settle.       

Again I am a little wiser on the Modern Wire Production Methods and after treatments for these Wires.
Cryo Treated is a method where a Wire is exposed to be frozen to a specific temperature.
Nano Treated is a method where the Wire is exposed to being Heated to a specific temperature.

The PC Triple C Power Cable I am using has a reference that states it is Nano.
