Just kidding. Seriously, it will be nice if the mod can maintain the advantage of eliminating additional USB cable.
My theory is that so called "audiophile USB cables" do, to varying degrees of success, one thing - reduce the interference that the power wire has on the USB signal wires within the USB cable. This power wire is carrying less than clean power the quality of which depends on the computer's/laptop's switched PS. Standard USB cables aren't concerned with this.
So the advantage of the Hiface is that this power only runs over a very short distance & lessens the potential for interference with the parrallel USB signals D+ & D-. It's unfortunate, however, that the USB design dictates that the power pin is right next to the D- pin so there is still potential for interference given this proximity, even with a short parallel run as in the Hiface direct connection.
My cable eliminates the power from the cable altogether (it doesn't try to lessen it's influence ) - no power coming out of the PC on the USB cable = no chance of interference with the USB signals. The power itself is external & can be chosen by the user so no reliance on the variability of different computer power supplies!
The laptop has one advantage - you can run it from battery rather than the SMPS brick. But even with batteries there are lots of switching regulators on the motherboard. Look at what providing clean power can do in audio - see slim's review & other end-users on the modified Hiface
Let's see what slim says about the cable when he gets back off holiday - maybe I'm completely wrong?
Oh, BTW, I don't think the Hiface plugging directly into a USB port & sticking out from the laptop is a good idea - too easy to knock it & damage the Hiface/laptop & also puts a lot of strain on this USB port/plug that over time will probably cause problems - see slim's experience.
