Under the same conditions, would pair of LHG XL 5 ax perform better than pair of LHG XL 52 ac ?

No, nv2 is better.

I'm not sure I understand your reply.

First of all, ac and ax devices don't work well with NV2 protocol.

Second, I'm interested in comparison of these two models only - is ax bringing improvements over ac, if everything else is equal ?

Currently I have pair of LGHs XL 52 ac which I can sell and I can get LHGs XL 5 ax instead. Is it worth the hassle or not ?
