This requires no skills and I find as good as anything that is supposed to do the similar job. Out of streamer/PC AQ dragontail to AQ jitterbug. USB A/B cable to this https://www.cdw.com/product/startech.com-4-port-usb-2.0-hub-hub-4-ports-hi-speed-usb/1303736?pfm=srh Ask to get it for $17 they should oblige. then go to Ebay and find an old multi voltage Radio Shack "regulated" IE, Linear Wallwart the 800ma one. or use Linear power of your choice but the RS one is very good. IFI PSU's are junk though. You will need correct "adaptaplug". Any electronics store should have it. Do not use more than 5V! Cut the Vbus by inserting a tiny piece of paper in the jack of the Dragontail to the Jitterbug on pin 1. If you cut ground many DAC's may not function. Make sure you cut it unplugging PSU to check. Then cable out to DAC from USB Hub. Can also put 1TB flash drive in furthest port from DAC cable to play clean music that is also isolated. Very little skill required here. Notwithstanding cables, total cost less than $50. I find this equal to Uptone, W4s, IFI ETC. YMMV of course. Hope this helps anyone. Don't knock it until you try it!
