• Introducing a customizable two umbilical high current power supply that is somewhat unique.  Customized MOSFET commercial power brick allows for clean power, immediate current on-demand yet in a sleek compact space.  This design is ideal for digital equipment such as modems, routers, streamers, DAC, and digital amplifiers!

     

    Each umbilical is digitally adjusted by the user by 0.1V from 5V to 24V - total demand is 6 Amps continuous (up to 10A for brief demand by digital amplifiers).

    Waversa H/P Power Supply

    • I’ll start with the WLPS H/P. As noted, I was using an Sbooster to power the 12V Technicolor Gateway modem/router. The Gateway serves both my TV set-up and my stereo systems. I use two 1m lengths of Nordost Heimdall 2 ethernet cable between the Gateway and the TV system. Between the two lengths of cable there is an EMO medical LAN isolator to break the ground connection and prevent noise from the TV system travelling on the ground from going into the stereo systems, as well as prevent ground hum caused by the systems being on different circuits. It works, too, for the hum anyway: hum in the main system without and none with. I have two 20ft lengths of custom unshielded CAT6e cable (one with ferrite ring), also joined by an EMO isolator, from the Gateway to the WRouter, 40ft of Audioquest Pearl with the shield floating at one end between the Wrouter and an Oppo player in the TV system (for two channel music there), and 20ft each of fully shielded Audioquest Pearl and Forest joined with one more of the EMO isolators running from the Wrouter to the DAC3C in the office system. The Sbooster made a big difference in all the systems in all parameters over the standard wall-wart, and that included with video. I think the improvements all stemmed from a lowering of the noise floor. I don’t have measurements, but it was easy to go back and forth between the Sbooster and the wall-wart to verify my impressions. The Sbooster was absolutely a keeper.

      Not long ago, John Ketcham of Kevalin Audio offered me the opportunity to try the Waversa hybrid LPS, the “WLPS H/P”, and (not very) long story short, I bought the Waversa and sold the Sbooster. While the difference between the two on the Gateway was not as large as the difference between the Sbooster and the wall-wart originally, the sonic and video benefits of the Waversa LPS relative to those of the Sbooster were still obvious and again across the board. I was surprised by this. The Waversa has a high-power third-party switching supply plugged into the wall supplying the internal Waversa-made LPS, which also applies filtering. That’s all well and good, but I’m not sure how the LPS actually works, or why this hybrid unit should react better in my system than the Sbooster “pure” LPS. However, I’ve read from some other designers/manufacturers that an LPS really is not the best solution for a digital device; they recommend using only the switching supply that accompanies their device or they have adopted some form of hybrid power supply. Anyway, the Waversa also operates from 5 to 24V (custom variable) with two output channels capable of simultaneous operation and up to 10 amps output for each channel. If I want to power another device at some point, I have the facility to do so without needing to purchase another LPS. While I was writing this, a Google search gave me a Korean article that provides more information and was apparently written for Korea’s HiFi Club (there is also a HiFi Club video review by the same author). I utilised Google’s translator to read it: http://raheader.egloos.com/v/4438735 More info (including a video) can be found directly at HiFi Club:
