Sound quality: Samsung's MX-ST5CB had acceptable overall sound quality - this model reproduces music and dialog reasonably well despite the obvious shortcomings in its sound. In the Standard sound mode setting, bass has good impact, and goes deep, but is somewhat prominent and tubby. The midrange is fairly even, bus is somewhat hazy and congested, and a bit grainy. Treble is fairly extended, but is a bit subdued and smeared. Does a so so job recovering room ambience, sounds somewhat congested. When two units are used as a stereo pair the sound stage can be made wider depending on placement. No significant difference between Bluetooth, Aux, RCA, and USB sound quality. Provides a decent volume level in a large sized room.
