I own the RA-55 and have tried several cables, but unfortunately not with ML equipment. A friend of mine, however, has a system very similar to yours LFR; RA-55, ML-380, and ML-333. The speakers differ dramatically though.
The cables he is using are Analysis Plus Silver Oval IN balanced interconnects, and I believe Oval 9 speaker cables. His system sounds absolutely wonderful.
