Thanks again, I had to actually reposition the order of the opamps to get the offset low. Its a little off because i have to have OPA627 in the left channel and the OPA134 on the ground and right but that order is the only way i can the dc offset low. If i change the order up, there will always be one channel with a high dc offset if bb is up.

In case you are wondering the suboptimal opamps setup, I have a few buddies who said they could give me some OPA637 samples.
