B19 is a new milestone! In my setup there's almost no jitter artifacts (unnatural highs, sloppy/boomy bass, masking/veiling, artificial bloom).

B18 uses a much smaller L2 cache 'footprint' which is exploited in b19. Changes in b19 goes back to my original design goals - I guess it works now given all the efficiencies gained.

Every transport has a jitter profile (with the worst being CD spinners). With computers, the 'default' environment is a source of jitter - cMP effectively addresses this and more. In a cMP setup, the audio player becomes the largest jitter source. This jitter is induced by digital logic. B19 excels here.

I would recommend doing as much of cMP's implementation in your setup. Using cMP's software (which runs on any XP computer) with Optimize set to Critical is very important.

Also, set your volume to -0.5db and not 0.0db as this allows for interpolation to occur where sound is at 0dbFS. Otherwise, clipping is done. There's far too many recordings with sound peaks regularly at 0dbFS or worse, clipped.
