Yep, the ORIVETI BASIC model review is in the makes and might be online by the middle of the next week.
Sub-bass and lower midbass quantity are comparable, however the BASIC has got the less full lower mids/root. The Zero has got the more pronounced 8 kHz and 3 kHz range, so it will sound brighter in the treble.
I find the BASIC's treble to be more even and natural whereas the Zero's is a little less natural. In terms of bass speed/tightness, the Zero is definitely ahead. Detail retrieval is probably a bit higher on the Zero's side as well.
The BASIC's soundstage is somewhat more open and spacious to my ears.
Personally and therefore subjectively I prefer the BASIC more though (the Zero is a bit too forward in the 100 to 500 Hz range for my tastes), even though I would give the edge to the Zero when it comes to technical level.
[...]
Might be that the Hidizs probably has a moderate roll-off in the highs, or what could also be is that there are more than one versions of the Zero (iIrc, one member mentioned that he bought two, one from Penon and one from Massdrop, and that both differ in diameter, so it could well be that Shozy was also experimenting with (slightly) different tuning options with the pre-alpha/beta versions of the Zero).
No, the ["old"] PRIMACY is definitely in a (much?) higher league overall [compared to the BASIC], but also differently tuned than the BASIC (more forward upper midrange, less emphasised bass). [...] Very enjoyable for the price indeed nonetheless, although not perfect (the bass is a bit too soft for example, nonetheless I really like it and think that it is the successful turn-out of what the Brainwavz M100 wanted to be but failed to achieve).
