How is the grounding on your amp? The hand waving is a dead giveaway of improper ground.
I never saw a big difference with R10 - that's simply the Class-A bias on the opamp, but it's good that it worked for you.
I would still take a look at grounding and before deciding on the OPA637 (only for Left/Right - you can't use 637 in ground, 627 can be used), I would highly recommend trying the AD825.
Photos would also be great.
Oops... I meant I changed R11L/R/G from 1 kohm to 100 ohm, sorry &
I have OPA627AUs on BrownDogs already, didn't have time to solder OPA637AUs yet . Well, I got OPA637AUs for free (well, almost and I happen to like them. I admit I have not listened to AD825. The problem is that this part is not available in Finland.
