The ls50s do what they do very well (very lifelike detail and coherency) but are small and thereby necessarily limited. Not designed for larger rooms. Yes they also require some muscle to be driven well. They will not shine otherwise and will likely sound downright underwhelming in larger rooms. Even in a smaller room a sub is needed for bass extension. I suspect many have bought these based on the deserved rave reviews and but with unrealistic expectations.
Have not heard those Pioneers but they are larger and likely not as challenging to drive so would not surprise me if they perform well with lesser amps but I would expect a much different sound that some might prefer especially in a larger room.
Apples and oranges are hard to compare.
