Synergistic Res. PC's, UpgradeI to X series?

Yes,

There is a substantial improvement in upgrading to the active, X-Series, power cords. I have upgraded or replaced the following (Master Coupler, Res Ref MK II, Des Ref Squared). In all cases, there is a lower noise floor, more transient information, and a wider and deeper soundstage.

If you have more than 2 cords, or ICs, which are active, the Master Control Center makes a big difference over the wall warts.

I believe, that there were not any active power cords, until the latest x-series.

Cheers,

Tom

I went with the new active, x-series verison of the master coupler on the MCC. I was really surprised at the difference.
