Belkin cables should be fine for the purpose.. Belkin USB cable is better than some branded / Belkin surge protector is better than russ andrews / Belkin toslink is better than any local one... So go ahead and let us know the results.
Buy Belkin.. But I suppose all the 3.5mm to RCA are out of stock in all the online sites like theitdepot flipkart.. anywayz check out again.. Or buy from local computer or audio video stores
There are also good brands. I just bought a 2 meter Belkin 3.5mm to 2 RCA from ebay.in to connect to my laptop. Price is around 395/-. It is also available in deltapage.com for the same price.
