I'm posting this on behalf of Ken Lyon from Neuance:
The "break-in" phenomenon reported for Neuance is real and often not at
The reasons largely amount to the rapid temperature and air pressure
that occur with air transit and also to a smaller degree, how heavy the
component used and how it is installed(ie-supported on spikes, laying
on a tabletop,etc).
The device is constructed as a torsion box operating in shear with a
multi-layered shell encasing a graduated density foam material in its
What happens is that the air trapped inside the cells of the foam core
the device will expand at altitude during shipping and stress the
bonds and laminates.
How each layer of the laminated shell makes contact with the next
layer determines how smoothly and evenly that energy is passed onto the
where they are damped.
When it's first loaded by the weight of the component, the individual
that make up the outer shell will be placed under stress, bind up and
gradually relax one layer at a time until all have equalised in
tension.Until all the layers have solid and even contact each other,
transfer and absorbtion may be spectrally uneven.
Thankfully, "break-in" is pretty much confined to the intial
and typically takes only a few days. I've had a report of as long as 2
in the case of one particular shipment that went to New Zealand.Then
again,others have reported no notable "break-in" issues at all.
