Samsung Guarantee V Richer Sounds

Richer sounds offer 6-year guarantee on the product compared to Samsung's 5-year guarantee.

I'm led to believe that the 6-year guarantee via richer sounds depreciates in value throughout the 6 years.

Would Samsung's 5 year guarantee be the same? Should I have went with Samsung direct?

Is one better than the other?

I've read millions of posts on here over the last few weeks and my head's all over the place. I'm thinking now it may have been better to have purchased it through Samsung.

Any advice would be greatly appreciated.
