I can tell you that the Venom are upgradeable in that I’ve done it, but I doubt that anyone here can give you valuable advice, but we can give you opinions. So, that is what I will do. First off, if you want to talk to someone at Shunyata, then call Shunyata. You don’t need a special code, secret EMail, or phone number. Second, I personally doubt that making one small upgrade of one power cord will be worth the money, or trouble. I believe that major improvements happen with major outlays of money, but should never be attempted without the ability to return what you bought. Lastly, I approached Shunyata as a power system where components were designed to function together. I believe that JB52’s opinion above is not to be discarded without consideration. It is best to start with the belief that making power cord changes is a waste of money and make the changes you make earn their keep, or return them. You can view my system to see where I ended up. When I upgraded, I didn’t make small upgrades. I really doubt that I would have seen such an improvement in the sound of my system with small incremental upgrades. I’m also absolutely sure that others bettered the sound of my system through more careful selection through the years and much more money spent. I think that today, top tier power products from companies like Shunyata, when compared to components plugged into the wall, makes for a clear convincing difference. Short of this, I suspect that a lot of money is spent on questionable improvements. Maybe there are products at 1/4 the price of Shunyata’s most expensive cables and power conditioners that will do the same job, but I’m skeptical. I do believe that companies like DH Labs might get you 80%-90% there for much less money.
