The discovery thread!

[AmericanSpirit]

Alambic Ears Mentawai

4 channels 11 drivers

Hybrid series-parallel filter

-A proprietary 10mm metal dome DD

-4 Knowles midbass
-2 Sonion tweeters
-4 SONION electrostatic EST
-Ergonomic 3D shell

Crossover: 4 channels
general impedance: 13 ohms
Sensitivity 112dB/mW
Freq. Response 20Hz〜40kHz

The latest addition to the brand, the Mentawai is the big brother of the Mundaka.
The metal dome Dynamic driver is retained but the rear damping has been modified.
We therefore find the serious Mundaka but drier and faster.
-The 4 low mids bring body to the whole.
-The double tweeter brings greater finesse and more richness in the details
-The EST quad brings ventilation, harmonics and improves the finesse of the main treble

Christmas came early






People need to know more about these.

4EST Price?

Audiosense AQ4, not a new IEM, it’s been there for a while. I was the lucky one to snatch one at exact same price with HEXA during AE anniversary sale from Audiosense official store.
It was $79 for 3 proper knowles +1DD.

15db of sub-bass lift is true! Immense amount of sub-bass. I will try to have the DD a stretch and see how it turns out.

Pretty nice calm tuning, gentle air, I like Juzear 41T’s tuning better but certainly like sophisticated AQ4 tuning as well.

It’s neutral with sub-bass boost nicely executed


Per tgx, you can play with AQ4 to bright shift. The overall note balance is very nicely allocated

AQ4 comes with mock-Sony-hybrids, so that’s another plus. I’m currently using AQ4 with stock the mock Sony-hybrid.

4EST Price?

€1690+S&H.

Made by 1 guy from France. Its a very impressive set.

Its similar to the Penon Impact and AüR Audio Alita and Trailii but with more energy and DD bass.

Wow…

The package of 41T is very artsy.

It looks like Gentlemen (君子不器) changed brandname to JUNEAR, then JUZEAR. Made in Shanghai. The city I was born

Junzi = 君子= Gentlemen.

匠音君子 means ”Maestro Tuning Gentlemen”

Wow!!! The shell is very high quality full-resinBlessing2 grade!



And stock cable is pretty high grade too.


Close shot.


Softears RS10 + Cerberus ….is that you?


Purchased at $139 from this global01 store. The name is very random but actually very trustable shop. I purchased Lafitear and couple of other unique IEMs from this global01.

The face value says $160 but it has $20 store discount so when you checking out, it will be $140.


Currently burning in the DD driver, it’s the type needs a good burn-in. Also the stock generic ear tip make bass boomy, changing it to H570 tips is highly recommended.

While burning in, I’m shocked right now, wow DA BASS Love it.

It’s 48ohms @113db. Crazy high imp for those love amps to run

Sonion 2356x2 for mid, custom 31735 for treble, and head knocking PSC 10mm DD (PU+Silk Composite ) .

Right out of the box, “yuck bass is nasty blurry, needs a initial run.“ 10min later.
””

I will post more updates later on.

So far, all I can say is, it’s worth it.
Here is the FR (Again, the db scale is questionable).


Here is Akros’s measurement for old model JUNEAR 41T for a better graphed one.

JUNEAR 41T (old model of JUZEAR 41T) vs Mega5P

Since there is mega5p on that cross comparison, here is mega5p vs SR5


JUZEAR 41T is soft timbre tuned for treble area, but that doesn’t mean it lacks air, it has great treble extension as I can see tuner at JUZEAR tried to compensate Ceberus’s Sonion EST by generating BA tweeter’s a air imitation.


It has a perfect 6khz sibilance dip, like Akros recommended 41T, I also can recommend march model of 41T by just listening it around 60min with stock cable and H570 ear tips.

You probably don’t need to wait my deeper digging, it’s good, just try it yourself if interested

Born in Shanghai, AmericanSpirit, using ChatGPT with Japanese prompt. Aren’t you Mr International

The graph is actually respectable. No deceiving intention here (unlike some brands and their strange axes). The actual FR looks very good too. I have little doubt it’s another good IEM.

---

3 borrowed IEMs from HiBy (plus the RS6 DAP, not in photo) came today. Impressive stuffs, especially the flagship Zeta (1DD + 4BA + 4EST). HiBy rep shared some convolutional impulse response. The increase in soundstage with this DSP is insane. The future might actually be DSP, like the fear of some manufacturers.

Will share graphs later.

Ahhhh, so you have gotten the surprise package! haha

Yeah, these are well-loved personal units for sure. Good to see how the RS6 hold up after however long it was used.

nice nice, looking forward to ur thoughts

Taking on these two beautiful multi-BA sets today, one has an 8-BA driver configuration while the other houses a 6BA driver configuration. One of these has lovely vocals, rich, dense, and crisp but lacks resolution. The other is way more balanced, has an excellent lower-end punch, and brilliant extensions at the top-end as well. The first one is the Kiwi Ears Orchestra lite, good sounding set for the price although lacks resolution and has an intimate presentation as well, the other is the SA6 MK2, well-tuned, has excellent bass, crisp instruments, and has good extensions as well.

Got the SA6 MK2 as a pre-sale unit(bought), and the Orchestra Lite is a friend's unit I got for audition.

wow! May I ask how does SA6 MK2 sounds compared to the MK1 or SA6 Ultra? you might be among the first ones to get hands on these.

I have the SA6 Ultra(sent to a friend for audition), it will reach me today and I will share the insights between them tomorrow bro. No experience with the OG SA6 though.

IMPENDENCE:48 Ω ???? can it be drived properly using usb dongle ?

 

[Leonarfd]

IMPENDENCE:48 Ω ???? any good using usb dongle to drive it ?

Should be easy to use from most dongles, sensetivety is high on it. The impedance is just one of the factors affecting volume.

Yeah, in fact 48ohm is the sweet spot for Apple dongle (design to drive EarPods, 42ohm). IEMs with this kind of resistance and high sensitive enjoy the least benefits from DAP or desktop setup, IMHO.

I lack the knowledge, patience and definitely time to tackle anything like this so I tip my hat to you, air if you ever decide to start selling your hand made cables, you can sign me up.

I am pretty sure I will not make any money selling cables any time soon due to my super poor efficiency, lol. It took me about 3 nights.
