I don't think the 571 style compandor works very well as a noise reduction system. The Roland SBF flanger uses this method and is still rather noisy.

Eventide used DBX type II noise reduction on their H910 and H949 harmonizers and the H910 delay sounds superb for a 10 bit system. Why not pick 
up a cheap DBX encoder/decoder and try running the signal through that pre/post your delay?
