as having been the owner of primus 150s, purchased on the basis pf the review in stereophile:

and having owned and heard other infinity models, i did so without hesitation.  they punched way above their fighting weight and could play quite loud.  the 363s might be on my short list but i will have to downsize from my current system soon.  i could end up with the ELAC B5s or B6s.  compact and nearly full range.

To be fair, the Primus line has gotten very good reviews for years from different publications, including Stereophile. As for the 160, IIRC Stereophile found it to have a ruler flat response. However since then Harmon upped the treble and bass. So the newer models should sound far from dull.

Ruler flat response does not mean they sound good.  Hopefully the newer models sound much better.   I have learned to be mistrusting of reviews as many reviewers try to be nice and write positive reviews on all the gear they review.
