I just received my Vision back from audio update. Audio is now at a comfortable level. I can now adjust headphone volume from 38-69. I live in North Texas, so it took 1 1/2 weeks from time I shipped till it returned today. Whites service depart can not be beat. It is always great to do business with White's. Rev is now 1.1. If you think your headphone audio level is to load I highly recommend you send it in for the update.
