I understand that the 2100 is easy to use and has good sounds but the previous PSR models dont seem to have as much punch and presence as some others such as the g1000 and solton. Is the 2100 technically any dofferent or does it have some more features? Also, why do other arrangers have more punch and how much more punch do they have and what do they have that gives more punch? When compared in detail there must be a measurable difference in how the sound is produced in each.

Thanks
