I personally more inclined to have “accurate” sound and word accuracy is more implies to a playback accurately and fatefully render the essence of musical events. Pay attention – not accurately play the input signal, not accurately play “what the microtones heard”, but rather the accurately play what I feel shell be played and what I recognize is important in given played material. In many way to do so I need to start with impartially of playback and then to enable playback to do what need to be done.
Yes, I absolutely agree.

Now, we are multiamping the system complimenting the MF-only DHT with IDHT LF and HF channels, of like Guy does with 845PP amps (let pretend that 845PP does not have this “timing randomness”). So, will the DHT’s randomness manifest itself in this application? The “timing” marks might be very much defused by IDHT’s timing in this case. My theory is that the “timing randomness” is the specific collapse or a specific build up of particular harmonic pattern right before or after the signal changes it’s dynamic pointer. Would the presents of other channel that does not comply with this “specific collapse or a specific build up of particular harmonic pattern” be a wrecking the effectiveness of “timing randomness”?
I doubt it, but it will certainly muddy things up, yes? Imagine an extreme analogy where we hook up just one channel of the LF out of phase. It confuses the picture but does not destroy the stereo effect of the HF (comparing to listening in mono to one channel). Yes, I know it is not a perfect analogy, okay.

The VERY INTERESTING idea is that the introduction of noise as a dithering element for the analog signal (for our brain to decode) can be helpful in increasing the retrieval of information vital to conveying the Sound. Perhaps different types of noise would be helpful for different types of information: a regular repeating noise to improve rhythm, a repeating amplitude noise to improve dynamics, etc. Well, I am just thinking out loud now. But the idea that we can introduce specific types of noise or signal into a system to enhance capacity for information retrieval is very interesting. We only need to figure out what kind of noise to accomplish the tasks to do the experiment.
