I just tried removing the STP cable between the switch and MS200/F80 and it seems something was lost. Re inserting it brought things back to life.
I can't put my finger on what has changed, it has never sounded anything less than great and it could just be a trick of the mind but for almost no cost the STP stays.
Does anyone know if longer or shorter runs are relevant here. I have a 5 meter length (�4.00 at car boot but it is a nice blue braided cable) but I can get a short length if it helps.
