And again, if this thread is about the Tool NO ONE can make a claim about it lying or reporting wrong results. That's false and misleading....Even if 75% of this forum or this thread is true, and greynol is most times right that doesn't mean the forum or Greynol's word equates The Truth.
.... so this thread is all about how the tool DOES NOT measure Dynamic Range. Now you say it does it right (?). Great.
Either it measures dynamics range and you have to accept filters and playback affects the dynamic range of a signal or what you are measuring is another thing. But you can not maintain both claims according to what you want to prove just to say to some of the audiophiles: f**ck you! They deserve. ok.. but that's not the right way of proving nothing.
Again the "real" definition of Dynamic Range needs not clarification. A CD has less SNR. If the same master is used in vinyl and CD, the CD wins. End. If this thread is here is because there is more to what we understand as Dynamic Range. There is perception and we are trying to measure it. Don't say now you don't want to discuss it.
What I am wondering is when there is a (non-clipped) peak with a fast rise-time in the signal, it's possible that the cutting head might fail to stop its lateral excursion at the correct point, and continue on for a while (due to a combination of inertia and insufficient damping). This would result in bigger peaks, and hence a greater peak-to-avg ratio. But I must stress that this is pure speculation on my part.
