While building my first pedalboard with a Pedaltrain Metro 16, I ran into the annoying problem of fitting the power supply beneath the darned thing. Using my Harley Benton Power Plant ISO-1, I've found that the supplied cables either don't fit underneath the board, or take up quite a lot of room while connecting with the pedal themselves, due to the connector being straight on one end, and angled on the other.
With these, everything fits perfectly, and it's looking pretty good!
That, and there was no aditional noise that I noticed when switching cables.
