In my oppinion, NO, it got very good reviews back in 2011/2012, i would keep it for the time being untill you are ready to upgrading your tv, i think you are just looking for something to spend your money on which is not needed.
I've got the same speakers. In my opinion, yes, you should notice an improvement when you upgrade to something like Yamaha RX-A2030 or 3030, or even RX-A1030. Demo first, to be happy with the improvement.
