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.

Spend some time with the new speakers in your system. Get to know them. Afterwards replace with your older ones. Listen to them for a while. Repeat.  Then the answer should become evident to you.

I brought the studio 100 circa 2004 home and was pretty disappointed with the resolution tho they did the job I found them boring. The newer models have a rep for being a bit tipped up so maybe you’ll like it better.
