Ventured into unchartered teritorry at last. 
Question:
Coaxial and Optical cable being digital, does a decent quality cable like belkin do the job or need costly stuff like analog cables to shine?
I have a 400/- HDMI cable and it serves me well. The length requirement will be 'shortest available'.
Are the below good enough?
Belkin 6 feet Digital Coaxial 24K Gold Plated Cable | eBay
Belkin AV10033-06-WHT Digital optical audio cable To slink, 6' White | eBay
Is there anything else I should be looking at instead?
