Last Saturday both of my Anker Astro batteries have been delivered and earlier this week I also received the Akasa eSATA enclosure and Apexi PCI/PCI-E bus power filter.
One of the batteries is now powering the Cubox through a home made cable in a USB A<->DC 5.5x2.1mm plug configuration. The other battery is powering the SSD inside my music server PC, also through a home made cable (USB A<->SATA power).
Today I starting looking at a USB Y cable to separate data and power. The Devialet's unfortunately need the USB power ground active (it can do without an active +5V from USB). Through coincidence I stumbled upon a 2nd hand ad for a Kingrex Unanimous Ucraft USB Y cable together with a Kingrex U-Power battery PSU. It has good reviews and new the USB cable costs around €600 and the battery PSU €199 but he sold both together for €250, a price so good (less than six months old) that I immediately called the seller and arranged the pick up!
The Kingrex is a cable that's 'dual-head' so at one side it has two USB A connectors, one for power and one for data. I can now feed the Devialet clean power instead of USB bus power out of my music server PC and/or the Cubox. And I can choose to use an Anker battery or the Kingrex U Power. I think the Kingrex is better as this one uses a linear regulator to "downvolt" the internal battery's voltage to 5V. The powerbank types of batteries usually use a high frequency DC-DC switching converter that of course generates it's own noise.
Sidenote, yesterday I told Kunter in the Cubox topic that I needed to slow down a bit because at the moment I'm changing things in both the Server2012 R2/AO/JRiver and Cubox/MuBox/MPD setups so fast I almost can't keep track of the differences created by each change, let alone describe them here at this forum. Today, by buying the Kingrex stuff, I failed in slowing down again! But now that everything is in house I can take my time!
For reference, for those interested:
