Good point. I have no idea if that 50 mA is steady, or an average. But if it IS steady it might not matter so much if it's also steady upstream. I'd put a low ESR bypass cap on the op-amp's own supply though, to help with that.

Platinum contacts and coated in kevlar and carbon fibre? Actually a carbon fibre weave would look cool, these things are sent to tempt us. But I'll settle for the carbon weave embedded in clear epoxy in the neck of a bass guitar, methinks. And there's not much room for caps in those either.
