Amplifier SMSL SA-50 Plus Black

SMSL SA-50 Plus is a neat metal block with a la loft finish. This appearance will allow the device not to violate the aesthetic integrity of your desktop, home theater, or audio system. The only blunder of the manufacturer in terms of design can be considered the controversial color inscriptions informing about the device model.

The layout of the controls is represented by a smooth volume control combined with a menu button, and three physical keys that are responsible for the Play/Pause command and track navigation. The set of communications (in turn) is represented by a micro-SD slot and a USB type-A port for reading MP3 files from flash drives and memory cards; 3.5 mm combined analogue AUX + digital Toslink input (an adapter is required for optical connection), as well as classic screw-type acoustic terminals. Naturally, there is also a small display that supports the automatic shutdown function.

Sound

Unlike many amplifiers of this class that use op-amp and PWM technology, the SMSL SA-50 Plus has a completely digital amplification path (Texas Instruments TAS5766m chip), which provides conversion to an analog signal using discrete elements such as filter capacitors. In addition to the components mentioned, the device is equipped with signal processors manufactured by Goke and ESMT, which are responsible for reading files (optics: AAC, WAV, WMA, MP3, FLAC, APE), general system operation and other functional aspects.

As for the direct sound characteristics of the device, the situation here is somewhat predictable, in a positive sense. First of all, we are talking about a pleasant, musically oriented sound, built on the basis of a justifiably V-shaped frequency response and tinted, warm timbres. Moreover, the amplifier will delight the audience with a good sound quality, the necessary punch, a spacious stereo image and the ability to work with multi-genre material.
