ST30 in living room, ST10 in Masterbath and now, ST SA-5 amplifier for the outdoor speakers. I am loving this system more and more. Seamless integration, all the music sources that I need and ease of use and set-up have made this the system I have been wanting ever since I started listening to non-analog music. Everyone's situations are different and we all have preferences and I believe there is never a 100% solution to things, but the ST line is above a 90% solution for my needs. Keep up the good work Bose and keep listening to your customers.
