yup ordered it , issue i have is some linear psu's are quite low at 5v/2amps and my tiny dac and headphone amp need to know how much they draw at max and allow some headroom
 
i have a similar device which iv'e had for years
the one i have is bluetooth which links to an app on my phone or pc
it works a treat and is great for measuring current draw / voltage etc as well as testing power bricks to see how close / far away they are from the real spec

mines quite old now but here is a more up to date version of it

Well I got it delivered and have plugged it in and it seems to give me the information I needed quite well
the screen is tiny but the current draw on my dac is tiny which i thought it would be only 1/10th of an amp and the draw on the headphone amp is about 1.3amp which again is excellent
so I have now ordered a nice linear psu with two outputs 1x1 amp max and 1x 2amp max @ 5volt

first image just the headphone amp
2nd with the dac included
