Williewonka, the operating principles of USB Disruptor would suggest that the type of USB cable from the computer into the Disruptor would not matter, so long as it's a certified USB 2.0 cable.
In my case, I tried several cables attached to the signal cable of the Doukmall cable and although the differences were small I could discern improvements between several cables - especially when using a higher quality DH Labs Cable.
But even the DH Labs cable did not perform as well as simply connecting the Doukmall Cable directly to the computer.
Perhaps the USB connector could have introduced problems? - I don't know, but it was very simple and a very short female/female adapter like this one

Without actually trying the Disruptor I am unable confirm your observations.
But I do believe the Disruptor achieves the improvements you cite and provides a very affordable solution alternative to overcoming the inadequacies of computer USB power.
