UEF Purple Duplex

Purple means power.

The Purple Duplex has an entirely new mechanical and material formulation selected during Double-Blind Testing, where we compared different duplex designs, choosing the one that sounded best. We then added brand new UEF Tech, first developed for our new SRX cable loom, and Purple fuses for a lower noise floor with enhanced soundstage scale and realism. We then applied the Purple Fuse’s Long Duration, High Voltage Conditioning Process. Hence, the new Purple Duplex shares the same house sound of high resolution with rich musicality as our Purple Fuses. Lastly, we went with a floating ground design so that noise from your wall junction box is isolated from your system: the net result is the highest resolution and most musical duplex in Synergistic Research history.

UEF Carbon Fiber Duplex Cover

  Science Makes Silence.


“Everything matters” as the saying goes and like almost everything else in life today, somebody is always looking to stretch the envelope of what’s possible. Ted Denney is one of the fastest horses within the high-end audio race today. I’m not at the finish line with insight into every variation in these different categories, but the Orange Duplex, the Carbon Fiber Duplex Cover, and the MiG SX footers sound like they could be near the limit of “what’s possible” at this point in time.
