Hi,

I recently bought the following product
http://www.google.co.in/url?sa=t&rct...KL9vvA&cad=rja

The product specification says

Audio
• Analog stereo output
• Signal to noise ratio (1 kHz): > 90 dB (A-weighted)
• Dynamic Range (1 kHz): > 80 dB (A-weighted)
• Frequency response: +/-0.2 dB
• Digital output: Optical
I want to buy 5.1 ch speakers and want to connect to Digital output: Optical. Please suggest which cable I will need. i.e. what name for cable should I refer

Also media player supports

Dolby Digital Passthrough Yes
Dolby Digital Plus Passthrough Yes
Dolby TrueHD Passthrough Yes
DTS Passthrough Yes
DTS-HD HR Passthrough Yes
Which 5.1ch speaker set should I buy with Digital input: Optical which decodes the audio as media player only passthrough the audio.
