Not necessarily. Your Pioneer is a pretty solid component. My advice would be to try before you buy, and don't expect miracles (especially since you're already pretty satisfied with the sound).
Some of Outlaw's products are very similar to products made by other manufacturers. For example, the monoblock amp looks like an NHT without the balanced input. It wouldn't surprise me if they license designs from a number of established companies. Nothing wrong with that if they're giving good value, which they certainly are.
