Description
The N6iii features a 4.97-inch display, noticeably larger than the 4.2-inch screen on the
N6ii but well within the one-handed operation limit. To avoid getting bulkier, Cayin eliminated
any structural extension around the chassis, giving the front an all-screen appearance. To
minimize the width of the DAP, the playback control buttons, and volume knob are tucked
beneath the screen. The curved sides improve grip, ensuring that even with a slightly larger
screen, the device remains comfortable to hold. As a result, the N6iii delivers a superior visual
and control experience, while its size increase is minimal. In today’s era of ever-larger DAPs,
the N6iii retains excellent portability.
One of the N6iii’s most significant design breakthroughs is the development of a new
quick-release locking mechanism to swap the audio motherboards swiftly. Fortunately, we
have dealt with a similar problem when we develop C9ii and we can modify the “tool-free”
quick-release latch into a three-point locking mechanism with a self-locking push-button
system, completely doing away with the need for screws. You can watch the video below to
see how incredibly easy it is to switch audio motherboards on the N6iii.
The N6iii also has a unique antenna design. In earlier models like the N6ii, the antenna
was integrated into the upper back section of the device, with relatively low signal gain to
avoid interference. In more recent models (N8ii, N7, N30LE), Cayin adopted an external ring
antenna placed on the top of the device, providing high gain and interference-free audio
circuitry for a better online streaming experience. For the N6iii, due to strict size limitations,
the antenna has been moved to a semi-exposed area, right beneath the top panel of the N6iii
DAP. While this placement results in a slightly lower gain than the external antenna design
used in N7.N8ii and N30LE, it offers a significant improvement over the previous N6ii without
increasing the length of the DAP. It offers excellent streaming performance with minimal
interference with analog audio processing.
E203 Audio Motherboard: The Evolution of ESS SABRE Technology
The E203 Audio Motherboard takes the N6iii platform to the next level with its integration of the ESS ES9039SPro DAC chip, delivering ultra-high dynamic range, ultra-low distortion, and pristine sound quality. The E203 introduces advanced features such as a custom I/V conversion circuit, LPF, and buffer stages, which further enhance the performance of the ESS chip and refine its tonal signature.
In addition, the E203 incorporates Dual Amplifier Operation (DAO), offering three selectable modes: Class A, Class AB, and Hyper Mode, giving users complete control over their listening experience, whether they prefer a smooth, classic sound or a more dynamic and energetic presentation.
The advantage is that the control range for each stage is smaller and more precise,
ensuring a smoother volume adjustment process. This ensures the left and right channels
maintain consistent signal levels across the entire volume range, delivering clearer, purer
sound with enhanced transparency. The Nisshinbo NJU volume chip being a passive device,
is very compact. Its low power consumption and low heat generation make it an ideal solution
for DAP implementation.
