Haven't been on my bike in a while due to injury and have upgraded the components in the meantime. Took my first ride today and the drivetrain whirrs like a small engine. It's not too unpleasant, but I kind of like it quieter. Could it be my chainring? I heard that the DA's aren't perfectly round, hence noisy.

Components:
DA chainring 1/8"
ESH Izumi chain
On One cog 3/32"

I think a few people mentioned switching to Sugino Zen's quieted their drivetrain, or maybe I should just let the drivetrain settle a bit? Thanks.
