Haven't fitted HEL but did fit Goodridge hoses. Far better brake feel and when heavy repeated use, pedal feel is far improved. Just have to complete the upgrade this time round by using Motul RBF600 brake fluid.
IIRC someone had talked about HEL hoses before but only one member and not sure they had fitted it to their RS4. I doubt there is too much difference between HEL and Goodridge so the theoretical and hopefully improvement would be the same?
