I use the balanced outputs to drive my DEQX (stereo xover), the differance was apparent to both my wife and I. The balanced sounded "fuller" with better midrange punch. Perhaps this was a result of better electronics on the 990 XLRs or the DEQX XLRs. Don't know, but why not try it? You can just try a set of pro mike cables ($12 for shorties) If that works better in stereo, go for the outlaw cables!
