I have an uprated 1.5 hp whisperflo (same pump as the full rated 1 hp) for may main pump and a 1 hp pentair pinnnacle, also uprated to it is equivalent to a 3/4 hp full rated, for my water features/cleaner. The whispherflo is MUCH quiter than the pinnacle.
Edit: The Pinnacle is still a pretty quiet pump compared to some others I have heard.
