Interesting 2x2 grid to describe what a component sounds like ... do you agree

i stumbled into the following review of the audio note cobra combo amp -- by a site called twittering machines...

https://twitteringmachines.com/audio-note-cobra-lastly-the-best/

so please page down to about 2/3's through it... there is a photo of the unit with an interesting graphic shown -- posing a framework for describing where on a 2-dimensional sonic spectrum this unit sits --

axis 1 -- 'sonorous' vs 'vivid'
axis 2 -- 'euphonic' vs 'analytical'

this particular unit was plotted as highly vivid and somewhat euphonic

then, to further up the ante -- there is a linear scale below the grid -- where the center section is 'intuitive' and the ends of the scale, both directions, are called 'challenging'

i must admit this framework is interesting, if somewhat confusing ... i am not sure i agree that the two axes are mutually exclusive, they seem to have overlap, but there is some distinction -- the horizontal lower scale seems downright stupid to me

thoughts?
