This particular Zerozone linear power supply with toroidal transformer found on eBay is outstanding, with true audiophile performance. I use two of them: a 5V version and a 12V version, and in both applications the particular Zerozone PSU sounds excellent from top to bottom, with no sonic downside, and very good build quality especially for a low-cost $62 PSU. The only issue I found is the stock DC umbilical sounds mediocre when compared to other DC umbilicals I've tried. However, it's not so much the materials used, including silver plated copper with Teflon dielectric conductors, nor the stock DC connectors per se, it's the fact that the geometry of the stock build is poorly done. Rather than a proper twisted pair, the construction simply involves two wires run in parallel through the outer sleeving. This issue can be remedied by disassembling the DC umbilical, pulling the wires out of the sleeving, twisting the wires properly, then re-terminating the cable with the stock DC connectors. Doing so substantially improves performance, with no added expense. That said, while the stock DC umbilical when tweaked performs quite well, I would suggest a DC umbilical upgrade at some point if higher-performance is sought. The stock rubber feet should be replaced with audiophile-quality footers, as well. Another option is to install a 0.1uf Wima MP3-X2 capacitor across the L&N of the IEC inlet for RFI suppression, but it's not a must-do tweak, IMO.
Six different output voltage/current rating options to choose from:
1. 5V/3A
2. 9V/3A
3. 12V/3A
4. 15V/2.7A
5. 18V/2.5A
6. 24V/2A
I experienced no shipping issues when purchased from this eBay seller:
