Sound Impression / Comparison with TA1 and TA2
Tonality is warm and bassy with good mid bass and little sub bass rumble. Bass Quantity over quality, ie. can be better, speed is normal, when especially play back a very Bassy and Busy instruments track, mid bass bleeds occur. Vocals can sound a bit nasal. Weight tone is good and forward sounding Imaging and instrument seperation is good average based on the performance of the knowles 33518 BA.
TA1 is more mid centric with more crisp clear and clean vocal [both male / female]. TA has more midbass, bass will sound more full and slam, but bleeds into vocal occurs. [similarily the case for TA2]. TA soundstage will sound wider and better extended than TA2.
Timbre is quite natural sounding with a tint of metallic, very slightly. Male / Female vocals presentation is acceptable in most tracks, except when tracks that are heavier in bass [bleeding can be heard, vocal sounds nasal].
TA1 timbre sounds more organic and natural as compared to both TA and TA2.
TA Soundstage is normal wide and acceptable. Width, height and depth performs better than TA2, treble roll off somehow affects the sparkle and airyness, just slightly. Both TA and TA1 soundstage sounds and appear wider than TA2.
TRN TA is positioned as the most budget wise set in the TRN TA series. For a warm and bassy sound signature with no sibiliance at this price point is a good consideration for a wide range of music genre as well. TA2 with 2 knowles BA is a better and pretty attractive IEM with focus in its weight tone and concentration in sounding but sacrifies a bit soundstage in return. Mid bass bleed and early treble roll off are both the traits found both in TA and TA2. For those more into mid centric vocals the TA1 is still the best choice IMHO.
