Where to go after Anticables Level 3 power cords?

The all-time gold standard in power cords in that price range is the Synergistic Research Master Coupler. Its not the gold standard because its the very best. Its the gold standard because its so doggone good that its been made for 30 years and its still so good people sometimes pay up to $400 for them even the 30 year old ones. Its just very, very hard to beat - and it can be done but not without spending a whole lot more money. 

Because its been made for so long there's a lot of them out there which is good because people know they are good and so they tend to get snapped up pretty quickly. I've seen people with 3 or 4 of them for sale all at once still manage to get $275 or more. Its also good because they are sold worldwide and so your chances of finding one you can use are a lot better than most others. 

So there you go.

Look at used Furtech Purist much better.

I actually went down in price but up in sound quality (in my opinion and in my system, of course).  I had been using the Anticables Level 3 with good success for quite a while, but I decided to try a few other affordable cords out of curiosity.  Surprisingly, the Audio Envy Ocean-Elite 3P for $179 (6ft.) was a significant step above anything I tried and bettered the Level 3 as well.  There is a discussion thread active right now about the Audio Envy cables - they are certainly worth trying.  

Thank you, gentlemen, for your recommendations, direction is clear, will go.

+1, for the SR Master Coupler.     I have an active iteration, on the Stealth XXX, power purifier, that feeds most of my components.    Another on my Transnova 9505, subwoofer amp (wall-outlet-fed).     Neither are going anywhere, anytime soon.
