If your only concern is the audio, I wouldn't recommend going to 2SS for that. I don't find it as good as the Monsoon system was in my 2002 WS6 and plan to upgrade the amp and speakers in the future. The Boston Acoustics system does seem to be waking up a little as I use it more though. I find the HUD and backup camera extremely useful. Here are the differences:
Available as options on 1SS, standard on 2SS:
Boston Acoustics 9-speaker audio
Rear vision camera/park assist
Also on the 2SS:
Heads Up Display
Leather Seats
Heated front seats
Heated and driver-side auto dimming mirrors
Auto-dimming rear-view mirror, frameless
Console gauges
Color display driver information center
Universal home remote
