SMSL's New Design Headphone Amplifier

I'm sure you are no stranger to SMSL if you are very concerned about Amplifiers. This time SMSL launched a New Design Headphone Amplifier, H300, which is a fully balanced Pre-AMP & AMP with JAS HD certification.

Fully Balanced Design

H300 has 4 ultra-low distortion precision linear feedback circuits(PLFC). It provides less distortion and gives you a more restored musical experience. The distortion is as low as 0.00006%, and the A-WTD is as low as 133dB.

Powerful Output with Efficient Power Supply System

Each channel of the H300 uses 32 low-noise op amps in parallel, a total of 64 op amps for the power amplifier. It has a frequency response of 20Hz to 100kHz (-0.5dB). The high output power of the H300, is 16-ohm output power up to 10W, 32 ohms up to 5W. Also, H300 has a built-in high-efficiency and low-noise power system. Let its powerful output be supported by a raging power supply.

Three Mechanical Toggle Switches

SMSL has equipped the H300 with a three-position gain control, with the low gain optimized specifically for IEMs. Its switch is a classic mechanical toggle switch, accurate and convenient to operate. In particular, it also has a pre-amp function, which can be used as a Hi-End pre-amp.

Solid as A Rock

H300 has an ultra-compact design, very suitable for desktop headphone systems. High-precision low-temperature drift resistance, performance is not affected by temperature. This allows you to use it without worrying about partial weather changes affecting it. The headphone amplifier has comprehensive protections such as DC, overvoltage, and overload protection.
