OMG please compare GK100 to the planar IEMs S-6 and Talos, especially how detailed and resolving they are and which of them are more analytical / clinical.
those 3 are quite different. GK100 is most detailled and technical beast. While SA6 is bassiest-punchiest, brighter V shape, and Talos is the most boring neutral harmanish one.
SA6 and Talos are nothing to write about tbh....and BA mode is very bad. Technical performance of GK100 beat those quite easily. and yes its the most analytical. treble extend more since those 2 seem to drop rather fast post 10khz....
I did compare those 2 already, and might add the great Raptgo Hook X HBB, to some extend, its a logical upgrade to GK100 if you seek more bass, fuller more naturla mids and similar piezo treble but not as analytical way...as well as more open spatiality...
VS MAEAOS EAGLE (2DD+2BA-150$)
Simply put, the Eagle is like supreme downgrade version of the GK100, its a bright wonky W shape that put all details in your face, but in a unbalanced and uneven way.
Bass is less punchy, have inferior separation between sub and mid bass, less texture too, sub bass bleed way more on mid bass and lower mids and is less fast in attack. Mids are horrifious with the Eagle, they are more shouty, thin and fatiguing, timbre is off and tone too, and it feel more recessed, its all about upper mids here but shouty way. Treble is dryer, less extended more shouty and less generous in micro details as well as more fuzzy in definition edge, GK100 treble is cleaner, more extended, snappy and sparkly and more resolved in a effortless way.
Soundstage is wider, taller and deeper with the GK100 and feel compressed with the Eagle. Imaging is notably superior too, without a mid range scoop and it's crisper, more accurate in positioning.
All in all, their zero doubt that for 50$ more the GK100 feel like a TOTL IEM compared to the technicaly and tonaly inferior Eagle.
VS KINERA GOLDEN 2.0
The Golden is more neutral and mid centric, smoother and warmer too. The bass is less boosted, warmer in punch, less well define and notably more rolled off in sub bass. Mids are more fowards, lusher, smoother and fuller with a more natural timbre and wider less compressed presence. Vocal are way better with the Golden. GK100 mids is brighter and more detailed and transparent, have superior imaging but more agressive upper mids, dryer thinner timbre and more distant presence. The treble is way more vivid, snappy and detailed with the GK100, it make the Golden feel not very extended, lacking brilliance and airy openess, level of micro details is higher with Gk100 too, but overall dynamic is louder and can induce more fatigue than more buttery highs of the Golden.
Soundstage is notably wider with the Golden, but less tall and deep. Imaging is sharper and more accurate and crisp with the GK100.
All in all, GK100 is superior technicaly but not as cohesive and musical in balance than the Kinera which have fuller and more natural and fowards mids but darker and less detailed treble and bass.
