I have been very pleased with my PowerPlant 3 so I have no interest in switching to another brand.
I really don't want this thread to devolve into another objective vs subjective debate.
As an electronics engineer, I think measurements have their place, particularly in ensuring production consistency. But I long ago learned to trust my ears above measurements, particularly measurements made by people who make no attempt to correlate them with the way a product sounds.
I'd really liked to hear from folks that have experience with the P3 and one of PSA's larger models (particularly the P12).
