Default Nice simple parallel bridge config

Any notes you can give that I should consider on this configuration?

I've built this where X1 and X2 are 3 parallel configured LM3875 chips each.

A previous version of this parallel bridge configuration was driven externally using a DRV134 and it worked very well.

I used the NE5534 (for X4) which is not stable at unity gain but with proper bypassing it worked. It has since been swapped for the OPA134 which is magic. I have not put it on the scope yet (did not have access to one) so I can't tell if there are HF ghosts - surely can't detect it otherwise.
