Hilmar-at-Bose ... a temporary workaround. Simply keep the channel volume and the master volume on the remote at or above the 12 o'clock setting. The easiest way to get there is to set the volumes to about 2 o'clock and dial in the trims on the powerstand so that the playing volume is about right. That gives you some space on the remote to back it up some and also plenty of head-room when things get a little "hot" during the night. That should eliminate all problems with the spike. That also means that you can use the remote and you do not need to peg the settings at 12 o'clock. I know that this is an inconvenience and we are working full throttle to get the issue finally resolved for all affected users.
