The Zerozone looks like a nice power supply Duster at a great price.
I have had good luck using the HD PLEX supply that offers a variety of fixed and adjustable outputs, including a 5V USB output. Two of the outputs can be used simultaneously. More flexibility but, even though it is not that expensive by audiophile standards, it is still 6x as much as the Zerozone.

Image: Zerozone 100VA high-current linear power supply
The HD PLEX power supply looks to be a nice one, mitch2. Since it's a full-featured, high-current PSU, it's natural that the HD PLEX PSU costs considerably more than the medium-current Zerozone PSU. I also found a relatively inexpensive 100VA high-current Zerozone with dual outer heat sinks like the HD PLEX which is a must-have for high-current applications, and for medium-current applications if excessive heat is generated by a PSU. It's only $129 via eBay, so I'm considering buying one for my new Xfinity X1 CATV box audio configuration project. The outboard PSU I'm currently using for the X1 is a Newmar high-end marine communication and navigation 3.5A PSU, which is a nice sounding product, but it's running so hot for the 3A maximum load of the Xfinity X1 CATV box, I decided to mount a whisper fan on the PSU for peace of mind. I'm likely to get the audiophile itch to evaluate the Zerozone 100VA high-current linear power supply vs. the Newmar PSU for the particular application.

The Ebay seller "zhufan2015" is excellent...
I have made three recent purchases and all have been processed and shipped in a timely manor...
Thanks for the encouragement, RadioWonder. I think I'm going to pull the trigger and buy the high-current Zerozone 100VA linear power supply, even though a filtered IEC inlet of questionable quality is involved in the design. However, it may help filter digital backwash from a potentially noisy digital CATV terminal, if that is the case.
Somewhat different parts selection but the prices of the Zerozone units are great for what you are getting, especially for those of us who are simply replacing wall-warts with LPS.
The HDPLEX uses a 160VA R-Core Transformer and a bank of ELNA capacitors but I have no idea how those choices may affect sonics or noise.
