You're using the AD797 instead of OPA134 and the OPA2604 instead of the NE5532 yes? Can you please post links as to which chips did you buy exactly? Also, instead of OPA2604, have you tried other opamps? Im really interested in getting the warmest sound and hardest bass out of the H10 without sacrificing on much detail or clarity. However, reading reviews of the OPA2604, it seems like it isn't much different than the NE5532, and a better choice is maybe the OPA627.
