My own experience with ASR is a clean, smooth but bleached aural presentation; good without regard to cost but tonally incomplete in any case and not retrievable if your criteria for fidelity include holistic representation of the leading, middle and decay of a note, as well as many simultaneous notes together. ASR produces an illusion of fidelity rather than the actual facsimile of it. Very good. Very expensive for what you get. Not far enough on the arc of convincing musicality. But I fully understand why some people are attracted to the clean, desiccated sound of ASR along with many other advanced but flat solid state options similar.
