Hi shuggieb
Thanks for your reply. That's very useful information, as I have asked this question before, without reply (obviously not the upgrade people do?).
Your comments are interesting cos the 1050 5.1 system was only 4 stars from 'what hifi', and the review complains of poor integration. But if your using the improved sub ('i' version), perhaps that improved it?
Not sure about the 1050 (not 'i'), thou, as they are BIG speakers, and the wife would go mad!
I'm probably only able to go up to the 1020/1030, or 1020i/1030i versions.
Anyone tried that upgrade?
