16x Less Distortion Than Monoprice: The SMSL SA400


There’s nothing better than coming home at the end of a long day, collapsing on the couch, and playing a favorite album on a home good home theater system. Unfortunately, subpar equipment can create more frustrations than they soothe. Unshielded circuitry can pick up electronic interference, and cheap components can create unwanted noises like hisses or pops. It’s important to spend money where it counts, and there’s almost nothing more important in a home theater system than an amp. 

Introducing the SMSL SA400, the power amplifier that delivers 230Wx2 of ultra-clean output power. Plenty of amps boast about power, but not every amp can boast about clean power. At .003% THD+N, the SA400 has 16x less distortion than the Monoprice 300-Watt Studio Audio Amplifier.
