Audionotions 8.5 Reviewer Score
Gaea is bright, and at first, it might seem to be dry, but not in a bad way. I initially thought it could use more meat on the bones, but this tuning works very well after listening. Sinfully resolving. Great layering with top tier transients, dynamics, imaging, and separation. Mids and treble are amazing. Bass is very punchy but perhaps doesn't rumble as much as I'd like, but it is still quite nice. Lack of rumble in the bass is probably the only knock I have against Gaea, but even then, the bass response is incredibly fast and overall the bass is very well textured and incredibly high quality. Loved this on demo so much that I ended up buying my own. Very versatile - plays everything I throw at it with ease. Previously Owned

Clarity king with great sense of detail. An agressive listen but never sibilant. Great tight and fast bass, at the expense of sounding dry in the lower mids. Not recommended if you are sensitive to higher frequencies.

Easy to like tuning that isn't considered too safe with convincing vocal presentation, bass slams hard Not entirely coherent especially in the upper frequencies, subbass hits a little too hard relative to the rest of the frequencies

Super aggresive, exciting, v-shape, treblehead. Low-end is also very punchy and rumbly. TOTL technical performance with tons of details and OCD, but gets fatiguing. Shouty.
