The DSP has absolutely nothing to do with the sound or usability of the product. Does the HX EFX not sound good enough too you? More DSP doesn't solve the sound problems, it would only allow more of the same quality of sounds. They would have to re-write algorithms to get better sound, and therefore DSP isn't what you are looking for, but better algorithms. And if you need more DSP because you want more simultaneous effects that what the HX EFX offers, then frankly you are doing something wrong.
