I disagree with the suggestion to try other cables, system synergy is very important and you already have the Oracle interconnects and speaker cables which are superb and not overpriced as suggested, as well as performing outstanding in your system. Most of these recommendations have never heard a complete Oracle system setup and are just guessing as to how it may sound.I have the complete Oracle setup and would not change them for any other cables and I have tried to many to count. To answer your question, yes you will hear an improvement each time you upgrade your MIT ac cables, it is just a matter of budget.Give MIT a call, its free, there is no selling pressure and they will explain the differences betwenn the cables and how they will peform in your system.
