It’s happening to Softears RSV vs Truthear Zero inside me.
15x price difference, one is penultimate cohesive “single dynamic”like sounding masterpiece, another one is just Variation tuned dual LCP DD.
But they both perform in closer range when it comes to sound reproduction. I could only see RSV slighly wins in resolution, image positioning, diffusion field conformity. And my brain is confusing, this can’t be, I must in honeymoon hype with Truthear ZERO.
Follow up notes on this.
I’ve spent 10 hours A-B testing Truthear ZERO and Softears RSV on various source, and concluded Truthear ZERO is indeed high performing but not TOTL spec.
Here is why:
Unlike Softears RSV, image projection of Truthwar ZERO is colored, it has forward projection by default, to visually present it,
Zero has certain 3D expressions with forward projection which I can say it is 3D IMAX movie theater with THX system. Imaging will stick around screen area with 3D projections, you do have great surrounding speakers as well.
For Softears RSV, it is a precision VR simulator, original Tracks mix is directly rendered with 100% of accuracy.
Imaging appear anywhere as original mixing engineer intended, it can be nearfield, room ambience, concert hall, or open air. This is what TOTL’s capabilities in what other IEM is lack of.
Resolution wise they are not too far I’d say RSV has got A, ZERO got A-.
Also ZERO has intentionally lifted “atmospheric air” for 10kHz+ air/presence reagion. Of which many TOTL IEM also uses the same technic as a part of their overall “air “ presentation , say 64 Audio U12t, See Audio Bravery.
ZERO achieved to obtain “atmosphere” generated by its independent 7.8mm LCP driver, which is actually my fist experience hearing the well presented atmosphere by a proprietary LCP dynamic super tweeter.
It is phenomenal and Zero should not be evaluated simply as “one of sub$50”.
It is a technological advancement.
Anti-thesis for “BA super-tweeter” that is actually love/hate issue going on for centuries. This technological advancement is one of the offer to someone
▶︎wants a very good air and finesse, a clairvoyant views
▶︎doesn’t like BA / EST timbre, feeling BA/EST timbre is not natural & harsh/solid
▶︎feels single dynamic driver —unless you pay $1k — is incapable of rendering treble as hybrid/EST tribrids could do
The finesse presentation capabilities will deeply impact on high-res source, it won’t kick in for lossy source, I’d see this one of the reason why some people felt nothing special from Zero, letting aside the LCP driver’s heavy burn-in prerequisites.
