Overwhelmed and under experienced...


This post is in regards to power cables. Hoping for a bit of insight.
I’m relatively new to "better" audio. 18 to 24 months at best.
My system consist of Oppo 203. A Marantz 7012 with Voodoo Vision Digital. A Monolith 5X200 RMS amplifier (unit power cable is in question for) with factory cable. Tekton Design Impact towers for front channels and PSB towers for rear channels. SVS subwoofer with a Voodoo Powerwave power cable.
I run Morrow Audio MA2 interconnects and SP6 speaker cables.
With the exception of the Monolith being plugged straight in to a Cruzefirst receptacle in the wall everything else is run thru a Shunyata PS8 connected to the wall using a Shunyata Venom HC power cable.
My system is used roughly 50/50 for music and home theatre. Music is 95% steamed from Tidal using a Supra Cat8 ethernet from router to the Marantz.
I am currently looking to replace the Shunyata Venom HC I had been using for the Monolith amplifier that was moved to the Shunyata PS8.
Lately I have come across an overwhelming amount of interesting options. Everything from an individual named Marcus Tunis on US Audiomart selling Black Shadow cables (4 runs of mil-spec silver over copper with Acrolink poly rhodium plated terminations) at $300 for 3 ft. to a Lessloss DFPC original at $275 directly from Lessloss. A customer return he stated. Also on the short list is a Shunyata Delta NR at $625 new from Thecableco (my customer discount price).
There have been many others that I have read about. To many to mention.
Question is, how does one choose? I know AWG size isn’t everything. Geometry matters as well. Would I really notice that much of a benefit from the extra money spent for the Shunyata Delta NRs noise reduction? 
I’m overwhelmed!

I don't know as if this reply will be much help but....
The Cable debate is huge and as I was interested in new power cables for I spent days reading many hours the opinions on this site and many others.  Of course, the recommendations varied almost as much as the answer to the best speaker.  
I have purchased power cables from Black Sand (very satisfied) and Morrow (used and with additional 40% off at the holidays a great deal).  Unfortunately, the improvement I hear may be due to confirmation bias???  I spent the money so God knows I want it to be for something.

Flip side is I asked the great N. Pass about power cables. 

" Large gauge oxygen free with clean connection surfaces are what I use, and I find it adequate. Keep in mind that I am evaluating amplifiers, not looking to explore the variations that specialty cables might introduce."

Food for thought
I compared the Shunyata Delta and Alpha NR cables recently. There was a huge change in the system by switching all of the power cables. Amps, Pre Amp and Line Conditioner and DAC. The system sounded different.

In doing an A/B/C shootout of Stock Delta and Alpha my GF and I decided there was huge improvement with the Delta and Alpha vs Stock. However we both decided that the Alpha was really dark sounding for us. Vocals seemed really far back. Almost all of our music is of the rock variety. We ended up selecting the Delta NR for everything except the DAC which we went with the EF because I could get the cable through the back of the audio cabinet. 

In talking with a friend that I made her on the 'Gon, his MIT brother suggested cables as the last thing to upgrade as each of them will color the system in a way that may or may not make you happy. 
I do realize room acoustics play a much larger roll than most people realize, but this system is in our main living area and used daily.


GIK Makes beautiful things.

Many have touted the benefit of having a cable "loom" which uses all the same cables for each piece of equipment. I can't speak to this per se but I have gone to all Silnote power cables in my system and they seem to work just fine. They are good quality and don't cost an arm & a leg. I suggest finding what you like in your system and work toward making them all the same. That's my two cents.
IMO any well made heavy gage power cable with tight fitting connectors and is flexible enough for your application will do the job.I used to have Venoms also and noticed no difference between them and the stock cords.Plus they're too stiff.Cabledyne Synergy is what I have now at $200 each.The sound became clear,clean,and quieter.
The GIK diffusers and art panels are beautiful and would fit into any living space.I've got some on order that should be here next month and will start a thread about the results later.I've been fooling around with homemade (ugly) treatments for a while.They definitely make a big positive difference.
