Well the problem is your stereo is too loud...use it to attenuate your volume, not the master on your HD. It needs to be maxed.
Same applies to a mixer, send all your HD signal to the board, then the sound guy can pull it back with the input gain.
That said, I go XLR to the DAW. Some say they can hear a diff between 1/4 and XLR, some can't but I know that the physics are such that if you are carrying a ground with the signal the signal isn't the best, so use your XLR and for that matter, using them both. Why not go stereo, why not take adantage of the better signal and some stereo imaging? You paid for it, you got it, use it.
