Planned to upgrade to DeVore Gibbon X, but concerned about comment of base leanness

was going to pull the trigger on an upgrade from Gibbon Nines to the Gibbon X.  I like the Nines and believe the X will give me a little more of  everything I like about the Nines, especially a much fuller and deeper sound.  I then read the review in the Stereophile Recommended Components 2019 "He also noted that "the midrange driver and woofers are out of phase in the region where their outputs overlap," which might explain the impression of leanness".  I am concerned about the impression of bass leanness. 

Anyone listen to Gibbon X and if so your thought on bass leanness, or overall impression?

Auditioning is a real pain as it will take a whole day and due to a current medical condition traveling can be a real pain.  I may just end up taking a day trip and spending the night in a hotel.  If there is bass leanness that is a deal breaker....
