FULLY DISCRETE 24BIT R-2R DAC

The SE300 comes supplied with an R-2R DAC instead of a Delta-Sigma DAC commonly used in other players. R-2R DAC, also known as ‘Ladder DAC,’ offers natural yet dynamic Hi-Fi sound:

24-bit Decoding
48 pairs (23xR and 25x2R) of 96 ultra-precision resistors are arranged to create analog signals, realizing true Hi-Fi 24-bit decoding.

Ultra-precision Resistor Design
A&K inspected each specifically selected ultra-precision resistor of 0.01% error range for accuracy and precision.

Ultra-precision TCR10 Specs
To create Hi-Fi sound without distortions within such an extreme precision design, the SE300 comes with special TCR10 specs to minimize changes in the 0.01% resistor error range.

CLASS A/AB DUAL AMP MODE

The SE300 comes with Dual-AMP mode:

Class A Mode
Offers the best linear output, amplifying signals without distortion or loss of signal and providing soft, warm, and natural sounds for accurate reproduction.

Class AB Mode
Offers a powerful output with the added benefit of high efficiency, presenting dynamic and crisp sound with less harmonic distortion.

2-STEP GAIN MODE

The SE300 supports a 2-step Gain Level mode to create a perfect match for a wide range of headphones and IEMs. “Normal” and “High Gain” settings allow for high current output to create a powerful sound and excellent driver control. With up to 6 Vrms from Balanced connections, driving high-impedance headphones has never been easier.

OPTIMIZED FPGA OS / NOS MODES

The SE300 comes with exclusively developed FPGA and provides optimized OS / NOS modes. The FPGA uses an optimized, proprietary design over off-the-shelf semiconductor chipsets, and supports the most ideal OS (Over Sampling) / NOS (Non-Over Sampling).

NOS (Non-Over Sampling) Mode
Player reproduces the pure original sound without any digital processing, allowing users to enjoy true, unprocessed sounds decoded by the R-2R DAC.

OS (Over Sampling) Mode
OS mode offers partial digital processing that expands the bandwidth of the original signal to offer impressive details, with an expansive sense of space and crisp, clear sounds.
