Hi, I've decided to give Philips 963sa a try given its great price at B&H Photo (239-). I've just got it in and I basically cannot seem to be able to set up the sub properly for SACD playback. Every time I set my main speakers to large, it automatically switches sub off in Advanced Bass Managment menu. The only way to keep mains large and sub on is if ALL speakers are set to large, which makes not sense at all to me. Also, if I have mains at large and center at large it would allow to keep sub on, but as soon as I switch center to SMALL, this thing turns off the sub, which again defies logic. Anyways, I have Monitor Audio S8 for the main speakers and I would like to set them to large and all other speakers to small and sub to on. Is it possible with 963sa or is something wrong with my unit or its the feature of this Advances Bass Managment setup (which in that case in totally ridiculous).
