Silence is Golden

I'm trying to get my drivetrain as absolutely quiet as possible.
So far I've worked out an almost perfect chainline (w/ an new cheapo kmc Z chain) and perfect chain tension.
I'm running an old Ofmega chainring to a Dura-ace cog, the teeth are all in good shape. 42-14. Road pitch.
Still a little loud, though...
Does anyone have any additional suggestions or secrets for a silent ride?
I know it's pretty anal, but all I wanna hear are my tires on the road...

you lube it?
chains come with enough to prevent corrision while sitting on the shelf, not much for actual use.

i changed my cog the other day, which gave me a perfect chainline because the surly cog is a bit narrower than the soma i had on there before. while i was at it, i also decided to give my entire drive train a cleaning, and soaked and scrubbed my chainring and chain, then lubed up the chain. all of this made for an incredibly smooth and silent ride today. so nice!

On your chainring and cog (if it is alum) after a while little burrs will form on the side of the teeth.
Supposedly filling those burrs away with a fine cut round metal file will quieten the drivetrain and will make it even smoother. I have not yet tried this, but is was told to me by a crusty old track mechanic so I assume there is something to it.

Agreed. I fought with a noisey Z chain for a while. In the end swapped it out for a SRAM I had laying around. After a little break-in it was real quiet. I imagine the majority of chainline noise in a properly dialed in setup is do to roller quality. The cheapo KMC I had seemed to have really sloppy rollers that always pulled dirt into them (and the pin area in general)

try an Sram 8 speed chain, they're cheap and quiet. a new aluminum chainring up front might make it quieter too.
