I just got these PSB speakers and the subwoofer.  These are a big step up from my HK Soundsticks III.  More detail, with the ability to present delicate notes accurately.  And the sub, when adjusted to avoid distortion, supplements the bass well.  It is amazing what these small speakers and sub can produce.  The speakers and sub work well with my Dragonfly DAC.  Note that a proper cable for the sub is not included; fortunately I have an RCA cable that works well.
