Which Power Cables to sell

Guaranteed you will not be wondering if it is any better- you will be shaking your head in disbelief that anything can be that much better- or my name's not Millercarbon and you can come back here and berate me and I will lay down and take it.

Yes SR is that good. The Master Coupler is the closest thing to the gold standard of power cords you can get. Not because it is the best, but because it has been around so long and still commands value, because it is that good. Name any other power cord from 30 years ago still selling used for nearly what it cost new back in the day. Right. Crickets.

But as good as it is, still it is only entry level as far as SR is concerned. The last time I suggested it someone else said a $1k power cord for $250, what's not to like? That's pretty much an exact quote. Also true. Pretty much anyone else's you would need $1k to match a Master Coupler. With Synergistic however you are entry level. Your best bet is to simply look around for whatever you can find used that fits your budget. 

There is one little detail to keep in mind. There was a period of years where Synergistic was using Active Shielding. If you get one of those you need to know a couple things. One, its great. Really makes a big difference. Two, the MPC wall wart uses up an outlet. Later on they incorporated this into the cord itself, but a lot out there are the older wall wart versions. And three, if you do get one they can be modded by Michael Spallone with a very affordable and simple mod that replaces diodes and caps and cheap board with better quality parts and point to point wire. Huge and very cost effective improvement.

I don't recommend any one over any other one. Its more a case of what might fit your budget and plans. Given enough information you can figure that out for yourself. There is no right or wrong with these things but that doesn't mean there aren't better and worse ways of getting there. The trick is to figure out what works best for you. Nobody else matters.

Oh! This one is easy! Since you can't hear a difference, sell them both. Sell them all! No one should have power cords that provide no benefit. Since there definitely are power cords out there that sound so good anyone can hear the improvement you simply need to get rid of your crap ones and buy the good ones. 

Pro tip* (inside humor): Synergistic Research Master Coupler, used, around $250. 

*The phrase "pro-tip" is a joke. The recommendation is not.
