So I currently have a Sony SRSx3 and looking to upgrade to something that has a bit more fuller sound. I live in an apartment so not looking for anything to make the walls vibrate. Right now, I'm in between the Sony SRSx5 and Bose Soundlink II. The latter is a little bit on the pricey side so I'm trying to find something that is more comparable to the Bose sound but doesn't cost as much. Can any of you make some recommendations based on your experiences?
