ok, I'll try. I've looked at the thread long enough. There aren't any replies since there isn't a clear question in the OP.
As far as what option to take - w/o your needs, wants, budget, future plans, room size, speaker type, number and size preferences (from 2.0 to 7.1 and above; satellites, bookshelves or towers) - how can anyone know what's best for you?
Since you made your way here, my advice is the same as Mr. A.V.S CT-100 Guru's, sell yours as best as you can, and start from scratch either with another all-in-one or better yet traditional AV system using separates. There's always market for used BOSE cr@p due to great brand recognition and each part being very proprietary and pricey to replace directly from the manufacturer. Each of the little pieces you can sell will likely have a buyer.
Let's start with your budget and system preference.
