While five dither circuits were featured in the PowerSwitch D-TC Supreme, the Gold Signature only shows four of them, these, however, now being of the third generation. For all those readers who are not – or, not anymore - familiar with the idea behind the analogue dither technology: It originally dates back to the radar technology, where it provided a greater range. Here, active Tesla coils send out pulsating signals with precisely defined frequencies. These signals are sent in antiphase. This should significantly amplify the music signal and eliminate the background noise. After further analysis and study - and lots of listening hours - Ansuz has now developed the third generation of this technology by optimizing the most effective frequencies.

The Supreme and Gold Signature variants each feature two active cable Tesla coils and two Anti Aerial Resonance Tesla coils. In the new top-range model, the number of square active Tesla coils applied to the PCB as conductor paths has been increased by 50 to a total of 140. There are also differences in the active Tesla coils: In lieu of 60 active Tesla coils, the Gold Signature only boasts 32 of them, while 31 Active Zirconium Tesla coils have been added instead. Their zirconium rod is supposed to significantly improve the resonance behaviour of the coil and thus reveals even more fine detail information.

Since I want to listen to the differences between the switches and the cables in an unaffected way, I remove the Waversa Isolator-EXT-1, the ifi Audio LAN Isolator and also the two Ansuz' Sortz from my digital playback chain. I also unplug the ground cable of the Synergistic Research Active Ground Block SE from the PowerSwitch D-TC Supreme. But before starting the comparison, of course, I let the PowerSwitch and the three cables from the Gold Signature series go through a burn-in procedure for a few days of continuous use. During installation, I noticed that the Digitalz now comes with very high-quality cables for connection to the PowerSwitch's voltage output. Four conductors are available for transporting the low-frequency AC voltages generated by dither circuits, as it happened to be with the thin cables supplied with the D-TC Supreme. Also, the feeder cables of the Digitalz D-TC Gold Signature now even carry directional arrows.
