Dude,
Oh well. At least he tested the jitterbug in the right place where a reduction in jitter might matter. Unfortunately there appears to be no useful effect.
Tgris,
Most streamers do buffer data in memory to isolate the D to A process from any minor temporary variations in bits per second but jitter can and usually does still get introduced to the signal between streamer and DAC for various reasons so its up to the DAC to deal with any jitter introduced into its input signal and more and more modern DACs do just that by re-timing the digital signal just prior to conversion to analog.
