The SP17 boasts greater articulation, better image focus, and an apparent speed resulting from lower distortion and a lack of smearing. Bass definition and control are improved, and dynamics simply pop. And because it is so quiet, the music stands out in bold relief against a black background.
The SP17 is completely single-ended with five sets of inputs plus a Processor (unity-gain) pass-through.About this unit
