I am now using AudioQuest Slate cables in bi-wire configuration to my Mo Fi OML 1's. Removing the jumpers and having the bi-wired cables have opened up the high frequencies. When the jumpers were used with another cable the highs were lacking in detail and definition. I tried some short speaker cable as jumpers and there was an improvement but not as great as I hear with the bi-wire cable. Part of this could be the quality of the AudioQuest Slate but if a speaker is bi-wire capable I suggest you try it. You might be very pleased as I am.
