Advise before I regret

I bought a new pair of speakers paradigm premier 800 series in piano white to get a little brighter sound and replace my existing paradigm studio 100’s v3 speakers that are mint but a few years old so I went with a replacement. I just added a Yamaha aventege receiver 2080 and am anthem mc20 amp to drive them. Any adivice or experience which set of speakers is better. Before I sell the wrong pair I will
do a side by side comparison but just wanted to get some professional experience.
