My IE800 are not with me right now but from memory the connector pin between the main cable and the split to each drive is a TRS, hence you have more chance of dancing with the Queen Mother than getting a balanced cable. The only way to achieve it would be to cut the cables above the Y split and connect a 4 wire cabler to your connector of choice. This is of course a one way conversion!
Good luck and let us know if you take that route.
