It is very hard to go back to other earbuds when I am using TGXear buds with a proper setup like
Tempotec V6+A&K PA10. It becomes easier when other buds have that different flavor that Jim's buds are not offering...however, having
three buds from his works ruins that too. The
Serratus Black Sand, Sunniva, and Desolation Sound effectively cover all the bases that I can ever desire, eliminating the need to seek different flavors elsewhere!
Serratus Black Sand: Relatively less midbass slam in this trio, but subbass depth is quite impressive, and midbass slam is a bit more dynamic than the OG Serratus. The midrange is highly transparent but slightly more organic than the OG. It is more transparent than Sunniva, almost similar to Desolation Sound, and the notes feel a bit wider. The treble energy is also considerably more brilliant than Sunniva but nearly similar to DS. The difference lies in the presentation and the definition. Surely, SBS reproduces the details quite precisely, but the notes feel slightly flat compared to DS and Sunniva - their notes are more three-dimensional. Also, SBS sounds more composed compared to the high-octane dynamics of Sunniva and DS. SBS has the widest soundstage out of the trio, similar height, and less depth. Imaging is immaculate though.
Sunniva: The most organic-sounding one. Initially, the bass was full-on slamming but the midrange felt a bit veiled. But with time and burn-in the midrange has gained better transparency, albeit still the least among the trio. Overall sound signature is distinctly smooth, favoring a full and dynamic presentation with a slight compromise in the details. Using the Smooth foams on them. These have a toe-tapping signature right from the beginning, so mostly perfect for pop and rock. Because of the smoothened notes, they do not do justice to orchestral pieces. In the beginning, the sound might feel less detailed, however, where Sunniva top the SBS is the note definition - the notes of Sunniva feel more organic and full, so essentially more realistic. Even though the width of the stage is less compared to SBS, the depth is more, creating a slightly more spherical soundstage.
Desolation Sound: And here comes the boss. It is like the best aspects of both of the above put together! Highly dynamic, and the best bass I have ever heard on earbuds - slamming, powerful, deep, and on top of that incredibly textured and tactile! Midrange and treble have a realism that simply takes away my breath - considerably above the other two. Despite the slamming bass the transparency of the midrange is not compromised at all, but does feel very slightly less than the SBS, but way above Sunniva. Plenty of energy up top, but no sibilance. The notes have a very unprecedented robust definition with outstanding details! The soundstage is slightly less wide than the SBS, but quite open-sounding nonetheless, and the depth is considerably better as well. Not a hint of congestion anywhere, and the best imaging out of these three. This is the highest degree, the crème de la crème. The euphoric combination of dynamics, organic timbre, and details!
So now, tell me, why do I need to venture elsewhere when Jim gives it all? Really, these are a collector audiophile's bane and a thrifty audiophile's boon.
