Depends on your preferences. In this case the SS amp (A18) has the more stereotypical "tube" sound to it - warmer, smoother, more bass bloom. The Icon has a sweeter top end though, and can also be fairly warm if you turn up the output impedance knob. Soundstage depth is in fact a benefit of the Icon as well, though tube choice plays a large factor in that.
