i found the 506's with x-laser amps to be much quieter than my dt40w's.
just a data point.

The "noise" (acoustics) comes from physics. Every action has an equal-but-opposite reaction. So when you apply torque to the mirror, the mirror applies a counter-torque to your entire projector. In scanning this is called "reaction torque". Now if I place a set of scanners on a guitar body (which can kind of focus and amplify the acoustic vibrations) then it will become more audible. If, on the other hand, the scanners are bolted to a thick plate inside a heavy projector, the reaction torques won't create much acoustic noise at all.
I'M NOT SAYING that some scanners can't be louder than others. Some acoustic noise comes from mirrors themselves, which, if they are comparatively thin then the mirrors might vibrate like little speakers. Also, scanners that have higher inertia OR when a lot of power is applied, they will be louder than low-inertia scanners where small power is applied (again -- Physics -- higher inertia and stronger power/torque creates greater reaction torques).
In any event, the C506 has among the lowest inertia of any scanner, and the mirrors are comparatively thick (Chinese use 0.5 to 0.8mm -- C506 is 1mm or even 1.1mm...) and with 12 volt drive, the peak current only reaches around 2.75 amps. I guarantee you that, if these scanners bolted to the same plate as DT40, they will most definitely be quieter!
It's Physics!

suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.
