SMSL SP400
Fully Balanced THX888 Designt
SP400 not only features THX888 but also uses many 0.1% high-precision low-temperature drift resistors and components in the design. The PCB characterizes a 6-layer immersion gold circuit board and dual customized power modules. They can provide a stable and reliable power output guarantee. All the cost is only to achieve the desired HIFI sound quality, lower distortion, and listen to the natural expression. SP400 is not only first-class parameter, the sound goes to the next level！
CNC Precision Machining Aluminum Housing
The SP400 comes with a high-end visual appearance with an integrally formed aluminum alloy shell, which effectively prevents oxidation. The use of non-magnetic raw materials can not only shield the interference of external magnetic fields but also have no magnetic fields. It is also worth mentioning that the exquisite and durable SP400 features exquisite workmanship and delicate touch.
Noise-free Power Supply
The SMSL SP400 features two pieces of customized 24w high-efficiency low noise power supply, that guarantee excellent audio performance, and output efficiency. It also characterizes high precision low noise 256 level relay volume control. But in actual use, to make the volume more linear, the excess levels are shielded.
Highly Popular THX888 Circuit
The SP400 follows with THX patented audio amplifier circuit (THX AAAtm)888, a linear double amplifier circuit with feedforward error correction technology. It can eliminate the mechanism distortion of traditional amplifier circuits， and reduce harmonics, intermodulation, and crossover distortion.
Convenient Remote Control
SMSL SP400 characterizes a 1.9-inch color screen visual display on the front that shows basic information. It is also equipped with a remote control which follows with a better handle and better quality.
