Yes you are right but Grade matters my friend.As other friend said he had got RCA Connectors for 450/= a pair.right? similarly if MX had A ofc cable in the range of 130 /= to 150/= per mts 2.5 sq mm then you can have that Grade.Chines manufaturer are just job workers.They dont want to know what the buyer from him is buying.they know only one thing that what you ask to manufacture according to the specification they do it.the grade is the buyers decision according to the price tag and market compatition.
