Hi, my Beovision 3, which we use to drive a surround set up( comprising a pair of 8000's, a pair of 6000's and a cube  bass unit), is playing up again and so we are thinking about upgrading to a non B&O TV ( Samsung 3D)but we have a few questions:-

1) we wonder what else we would need by way of an AV amp to drive the existing speakers. one advisor pointed us to an amp with "pre outs" costing around £550 (Yamaha, Denon or Sony). Another told us to dig out an old second hand 5.1 pre amp/AV unit on ebay ( less than £50 for a kenwood unit).

2) will we need a centre speaker.....the role previously undertaken by the beovision 3's own speakers. If so , any recommendations and what sort of cost would we face?

3) Is there any way we could canabalise the Dolby Digital unit from the Beovision3...beyond my skills but wondering whether a TV engineer could separate the required modules into a working unit.

4) Im guessing the din sockets on the speakers would need to be changed. Any problems with that?

5) at the moment the speakers power up when the TV is turned on.  How will they power up without the TV?

All comments and any advice would be very welcome.
