Visceral and Emotional

Ken is genius…

Highly recommend…

Filters not trick

"
TRUE ISOBARIC Dual-Dynamic Bass: This innovative structure synchronizes two dynamic drivers in an acoustically neutral coupling chamber, achieving bass with exceptional depth, density, and impactful presence—well beyond typical IEM capabilities."

^^^ Another isobaric bass…

[ErKil]

What brand is this? Looks like a 64A Volür clone😅

[Rikudou_Goku]

Astell Kern? (yep it is,)

@ErKil

64A

Although you arent really wrong lol.

" NUARL’s unique single full-range dynamic driver

The unique “NUARL DRIVER [N10]v6” combines a φ10mm DLC (diamond-like carbon) diaphragm with a 7N grade (purity 99.99999%) OCC (monocrystalline high-purity oxygen-free copper wire) voice coil. The NUARL DRIVER [N10]v6 is a unique “NUARL DRIVER [N10]v6” that combines a monocrystalline high-purity oxygen-free copper wire voice coil with a powerful dual magnet magnetic circuit that uses the strongest grade higher grade neodymium magnets placed both inside and outside the voice coil to produce a highly detailed, yet rich sound.

Dual Chamber Driver Modules

Dual-chamber driver modules with two independent air chambers are installed by closing the front and rear sides of the driver. The dual-chamber driver module reproduces a sense of volume in the low-frequency range regardless of the size of the enclosure.

NUARL Phase Guide

The air chamber between the front of the driver and the nozzle is equipped with a unique NUARL Phase Guide made by 3D printing. This suppresses phase interference in the high frequency range and achieves both low distortion and efficacy, resulting in extended high frequencies.

■Hybrid HDSS

The world’s first hybrid HDSS with two 3rd generation ETL acoustic modules in the driver’s rear chamber and one in the front chamber is employed. This prevents distortion at high volumes and absorbs incidental sounds from the material, reproducing a clear, three-dimensional, natural sound spread over the entire frequency range.

■Selectable localization and volume

Includes two types of 4-step tonal nozzles (long and short) that can be adjusted by 2dB each only for bass sounds below 500Hz. This allows you to select not only the volume of the reproduced sound, but also the breadth and localization of the sound.

Stainless steel housing

The body is made of stainless steel with excellent rigidity, and is 5-axis CNC machined to create a combination of complex curves that cannot be achieved by casting or forging, thereby suppressing resonance inside the housing and creating a unique design that is easy to wear.

Thorough attention to sound quality

The drivers are aged for 100 hours before installation to stabilize the sound quality. The nozzle is made of brass to disperse the resonance point by changing the material of the nozzle and the chassis. For internal wiring and cable connections, 20% silver-containing Pb-free SnAgCu (tin-guin-dow) solder made in Japan is used. The cable uses a φ4.4mm gold-plated 5-pole plug and 7N OCC 0.06mm/7×7 8-core silver-plated copper wire for balanced stereo connection and is compatible with re-cabling using Pentaconn Ear. φ3.5mm unbalanced ⇔ φ4.4mm balanced conversion cable also uses 7N OCC 8-core silver The cable also uses a 7N OCC 8-core silver-plated copper wire."

Bravo CA

Rufige Kru - Secret Handshake (Visualiser)

Textured, layered, separated, pulsating, visceral bass… and a really very wide and deep stage with good height.

[SoundEater]

[publicpersonae25]

I looked it up to see what the specs are and have never seen such a dearth of information for such an expensive product. It’s not even featured on their own website. And tbh they look like a grade schooler’s arts and crafts project

[Rikudou_Goku]

That is one huge and noticeable line…

Simgot EW200 at 40 usd is even better…

Shame on them…

[publicpersonae25]

I totally missed that… I should have said: a grade schooler’s project looks better than that. Heaps of shame on them most definitely.

"Magnetostatic driver in IEMs, or in-ear monitors, is a type of speaker that converts an electrical signal into sound. They work on the principle of the Lorentz force, which causes a thin, lightweight conductor to move in a magnetic field when a current passes through it.

Here’s how it works:

• Diaphragm: This is a thin film with embedded electrical conductors.
• Magnetic field: A stationary field generated by permanent magnets.
• Motion: When the current from the audio signal flows through the conductors, it interacts with the magnetic field and creates a force that causes the diaphragm to move.

The movement of the diaphragm creates sound waves that we perceive as sound.

---

What sets it apart from other drivers?

Magnetostatic drivers, which are a variation of planar magnetic drivers, offer unique advantages, such as:

• Fast response: The diaphragm is extremely light and moves quickly, resulting in more accurate and detailed sound.
• Low distortion: The diaphragm movement is very linear, which minimizes distortion and provides a clean and faithful sound.
• Wide frequency range: They can reproduce a wide range of frequencies, from low bass to high treble.

While they have advantages, magnetostatic drivers typically require more power than other driver types, such as dynamic drivers, which may be a disadvantage for some users.
The Lorentz force is the force that acts on an electric charge moving in a magnetic field. It is one of the fundamental concepts in electromagnetism and is described by the formula:

$F = q(v \times B)$

Where:

• F is the Lorentz force (vector)
• q is the magnitude of the electric charge (scalar)
• v is the velocity of the charge (vector)
• B is the magnetic field strength (vector)

The “$\times$” sign denotes a vector product. The direction of the Lorentz force is always perpendicular to both the direction of the charge’s velocity and the direction of the magnetic field. Its magnitude is calculated by the formula:

$F = |q| \cdot v \cdot B \cdot \sin(\alpha)$

Where $\alpha$ is the angle between the velocity vector v and the magnetic field strength vector B.

Important characteristics of the Lorentz force:

• It does not do work. Since the force is always perpendicular to the direction of motion, it only changes the direction of the velocity, but not its magnitude. This means that the kinetic energy of the charge remains constant.
• It is the cause of the motion of charged particles in a magnetic field. For example, the Lorentz force is the basis of the operation of mass spectrometers, particle accelerators (such as cyclotrons), and electric motors.
• Its direction is determined by the left-hand rule. If the left hand is placed so that the magnetic field lines enter the palm, and the outstretched fingers point in the direction of motion of the positive charge, then the thumb will indicate the direction of the Lorentz force. For a negative charge, the direction is the opposite.

The Lorentz force is one of the fundamental interactions in physics and is key to understanding electromagnetism and its applications."

This DAC is as if created for AB. 1000% recommended combination.
And so you will see how far behind Chi Fi is from CA…

[Rinderkappajoe]

@SoundEater

And so you will see how far behind Chi Fi is from CA…

lol that´s a very bold statement

[SoundEater]

I’m specifically referring to dongles here. Demonstrate it if you can and you’ll see what I’m talking about.

[Rinderkappajoe]

I demoed that specific dongle in combination with Alien Brain
I still think that it is a very bold statement
What does it make miles ahead for you?

[SoundEater]

@Rinderkappajoe

What does it make miles ahead for you?

The sound, what else + combined with very good technicality. DС Elite does not manage at this level, but it is good nonetheless.
And one more thing - show me Chi- Fi IEM 1DD+4BA at any price, who does it like that.
