Question Without a HDMI receiver - best audio connections

Should I use the Optical or the 5.1 analogue ? The manual says Optical is slightly better but I had heard the analogue was better if you are without a HDMI receiver and are still using an old style one.

Optical and digital coax are usually the best for straight audio. (They are identical and just use different cables.) There are circumstances when analog audio could result in better sound but that is unusual. For example, if a BD/CD/DVD player has significantly better DACs that the A/V receiver, then analog connections would provide better sound. Analog connections might also be required for SACD and DVD Audio discs. Otherwise, it's better to go with the digital connection.

Thanks Bob. Can you True HD sound through optical or does that have to be through HDMI.

Dolby TrueHD, DTS-HD MA, and PCM tracks on Blu-ray discs can only be transmitted via HDMI or analog outputs.

It would help if you could tell us what components (make & model) you are connecting.

I believe that ScaryBob's post is a bit misleading since optical and coaxial can only carry compressed audio, while the multichannel analogue connections can carry the uncompressed audio. See the section on HD audio near the end of the following post:

http://www.digitalhome.ca/forum/showthread.php?t=76082

The issue then becomes the proper setup of all the equipment since most AVRs do no bass management, therefore the bass management and proper speaker balancing must then be done in the BD player and it's often not easy to find the right balance and the proper settings.

Of course the multichannel audio connections (6 or 8 of them for each of 5.1 or 7.1 audio) are not the same as the red/white analogue audio connections which are clearly inferior.
