Really interesting results! I've been really happy with the opa1622 on adapter(the green pcb with virtual ground made from caps on resistors on the adaptor.) I recently bypassed those with a wire so opamp ground is connected directly to amp ground. I think it made an improvement and it measured better. Have any of you made this socket mod and then compared the opa1622 modded to the opa1656?
