Compact & Packed With Features

Looking for an easy way to set up a passive bookshelf speaker system? The SMSL SA-50 Plus is an all-in-one speaker amplifier solution. It contains a powerful amp and a built-in DAC, allowing it to handle an entire audio system despite its compact size. With an output of 50 watts at 4 ohms per channel, this unit can power most bookshelf speakers without a problem. A step up from the standard SA-50, it features a variety of inputs that allow it to function as both a source and an audio player. As an audio player, it can read memory from micro-SD cards and USB drives, and these can be navigated using the front display. Plus, it can receive signal through the 3.5-millimeter aux or optical inputs. 

Note: At checkout, choose black or gold.
