i've heard both and agree with shadorne. the vienna is nice sounding and beautifully built and finished, but too laid back and reserved (mellow?) for my taste. the psb synch, on the other hand, is terrific--detailed, rich and dynamic sounding, big soundstage--among the best i've ever heard in the $2k range. needless to say, these are purely subjective judgments and your tastes may vary.
