You don't need to lower the volume on the 2410, and the dynamic impact is soft by comparison.
I did not realize there is a large difference between the C-2410 and C-2810 as Greg has mentioned.To give an example of the difference: the dynamic range and the hi frequency extension. Take the first movement on Mahler 2. At the ffff, the dynamics on the 2810 are such that you need to lower the volume. Also, the clashes are very sudden and scary if loud.
