Which of these power cords ?


I'm looking to upgrade my sound with upgraded power cords. Given I've got a tube preamp, 2 mono block tube amps, Aurender DAC and 2 Martin Logan speakers - we're talking up to 7 power cords so I'd like to keep the total cost for all of them to $1000ish. 

And some suggest going with one brand, to get the biggest benefit.

Brands on short list include:
Suggestions?

Contact Chris at VH Audio about his Trans power cable.  It is a new one and he hasn't posted the particulars on it yet.  I purchased one and it is the typical high quality that his products are known for.

My entire audio system equipped with Audio Art power cables.  They are very reasonable priced especially when they are on sale. Furthermore, the fit and finish are excellent. 
All I can tell u is that shunyata venoms sound much better than stock cables and also better than many well known brands which cost more.  I have replaced more expensive power cords with venoms and still use them and my system is pretty decent
harbeth super hl5 driven by LFD NCSE with a bel canto E one streamer feeding a moded bel canto DAC and a luxman DA 250.
The only power cord that has bettered the venoms cost over 1k and it is an audioquest tornado and it does not blow the venoms away
Venoms are one of the best values in this crazy audio world we a part of!!
In my experience:
A= Significant improvement in sound quality
B= Modest improvement in sound quality
C= Minimal improvement / No discernible change in sound quality

Shunyata (Alpha Digital, 2016) for my DAC= A . I bought this for $500 from Usedcables ( owned by The Cable Company, but with a separate web site). Best money I spent on PCs, but after a lot of trial and error.
Highly Recommended- choose the model based on the current needs of your component. Older models with Ztron technology are terrific. Haven't tried the new Venom, Alpha, ....line

Allnic ZL3000= B. Bought new from a dealer on Audiogon for $840- do not recommend because they are overpriced for the small improvement

NRG Custom cables, Canada. Bought for CDN$400 = B. Recommended, but don't expect "instant improvement" like you could get from Shunyata.

Zavfino majestic, $225= C Also not recommended.

Signal Cable= C. Not recommended

Amazon- W ? or something= C .Not recommended 

I strongly support the idea of auditioning cables from the Cable  Library with The Cable Company ( they also own the site www.usedcables.com)

Hope this helps.
