The only DSP modes that I've seen praised often are 5 channel stereo and cinema re-equilization. Some people may use other DSP modes to watch sports, but for the most part, none of the generic DSP modes (Concert Hall, Jazz, Ghetto Blaster, Bose ) are used often. If it was possible to defeat the DSP modes, such as have a menu option to turn them on/off, and if they added no additional cost to the unit, I would say 'Yea'.

However, there is no way that the inclusion of additional DSP modes will not affect cost. As others have already stated, extra DSP modes will require additional work on menus, more QA to be sure the modes work properly, and increased support for users who can't get their units out of "Men's Room" mode. In keeping with the K.I.S.S. principle, I say 'Nay'.
