panasonic BlueRay's

[kojak]

I'm thinking of getting a Pioneer 50" Plasma. (5090). I also need a Blueray.

The problem I have, is the amp is a Dolby Digital 5.1 Yamaha A2 which is 7/8 years old. It doesnt have a HDMI but does have an Optical Socket. I'm looking at the Panasonic Bluerays BD35 and BD55....or even an older BD30. Questions I have are:-

1 - Will I still be able to listen to 5.1 through my Yamaha A2 amp on the BD35 (no analog sockets)

2 - Will the sound quality, especially for music be better on the BD55 as its dearer.

3 - Shall I try and get a BD30.


Cheers
