Power Cord for Synergistic Research MCC

Hi Mick
I auditioned every one of Synergistic's AC cords with an original MCC just as you have. My rig at that time was not nearly as revealing as it is presently, yet the test results were definitive even then. I now have an MCC-MkIII. Click on my username & then scroll down below my bio if you want to know the present rig's complete makeup.
Anyway, even with my older rig & the original MCC, the difference between AC cords was quite compelling. I didn't really want to believe that the AC cord would make any difference at all, even after discussing this with Mr. Ted Denney Pres. of Synergistic. Was I wrong!
I began the testing with a cheap stock AC cord, followed by the Master Coupler, the Reference AC, the Resolution Reference AC, the Designer Reference AC, finally the Designer Reference Squared AC. All of these cords were obviously pre X-series.
Every time that I installed a better AC cord, the depth & staging especially improved over the previous cord. This was the most noticable difference, although there's a greater sense of naturalness imparted with active shielded interconnects regardless of which AC cord was used. I ended up with the Designer Reference Squared AC cord & realized better bass definition & extension as well with that cord. Go figure; I still don't understand it, but then neither does Mr. Ted have a complete explanation.
Having recently upgarded to the MCC-Mk-III, now all 3 of my Designer Reference Squared AC cords are active shielded as well. The new X-series is all seriously even better.

I have an early Master Control Center also. The early MCC came with the classic master coupler. I received it with a replacement power cord of an unknown source.
Though I have not tried the Synergistic Research power cords with it, I have tried different Brand Name power cords and couldn't tell the difference.
I could tell the difference between the active shielding being on or off with the ic's and speaker cables.
I could definately tell the difference with the Name Brand power cords replacing the stock power cords on my pre amp and cd player.
I'm not saying that there is not a difference, just that I couldn't tell the difference, the power cords all sounded the same to me.

Bob; thanks for the post. I also have just upgraded to the MCC 3, and consider it an imprtant improvement over the original mainly because of the quality BNC connectors. I'm glad to hear of your experience with the upgraded SR power cords as I'm just using the standard Master Coupler. I also talked to Ted Denney and he recommended the Reference, but I couldn't afford it at the time. Cheers. Craig

Craig I have a Reference AC (pre X) just sitting here that might be of interest...you're welcome to try it.
The MKII unit went to the BNC connectors & better DC control cables.
The MKIII they upgraded the internal module(s) to X-series (this can also be done at home) & X-series DC control cables, remarkably resembling their Synergy speaker cable. Cheaper build cost & better HF & LF extension as well.
Anyone presently owning an MCC Mk-II might be interested in an additional module (2 are available) if you want to power additional active interconnects, speaker cables, or AC cords. Y'all know how to find me.
