DSP and DAC are like painting by numbers. Building an analog crossover is more like painting a life model with whooping cough.
Anti skating compensate the force generated by the angle of the cantilever. It don't change if the disk has its groove cut from inside to outside.
I suspect vinyl will outlast CD, most of us could build a victrola like turntable but not a CD player. I had to search a bit for my wife’s last laptop to find a DVD drive model and windows 10 now comes on a USB stick, the pig won’t fit on a DVD.
My new car can at least play wave files from a stick but I do miss my 68 Olds convertible especially the back seat.

No, being alone in my opinion is not frustrating, reading criticism that is based on flat wrong premises but nevertheless repeated despite any correction effort is a bit.
Otoh, as I am still interested in dynamics of human interaction generally and in its internet variant, nearly everything provides additional information.
Who could disagree, but the bottom line is that no perfect experiment exists (most probably) and so we can't use the shere existence of flaws/ambiguity/unclarity as reason to dismiss any result per se; instead we have to evaluate what is reasonable and what will likely skew the results.
Speculation presented as fact?!
(see below)Thanks for the argument. I shared that reservation -not right from the beginning but after I saw a couple of years later the measurements you've linked - and read the publications again (including Yamasaki's contribution to the invention of the 1 bit process, I'm shure it was a team effort, but afaik his ideas) and both parties (Yamasaki) and the other authors emphasized the advantage of the pre-emphasis and de-emphasis process used wrt to the reduction of noise. As at least Yamasaki is IMO a trustworthy source I tend to accept it, but of course I'd prefer to have a full set of measurement of the whole chain they were using.
Especially today when the internet provides unlimited space for supplemental informations that can't be pusblished in a journal for various reasons.
Now we are talking!
Again he measurements aren't surely detailed enough and "flat" wrt the speakers might be a bit too optimistic when considering the response curve the authors showed in their convention paper from 1991; the speaker system used later seems to be more refined, but the of course the question remains in which respect that could have skewed the results?
IMO it's the same wrt GD.
Surely an interference effect occurs in the crossover region given the short wavelength in that frequency range, which is still one of my concerns.
But looking at the whole picture given by all the test results in their experiment it seems unlikely that any interference was the reason.
Let's see, presenting the HFC alone (via the supertweeter path) provides a control and in that condition any GD concern is moot or would you argue differently?
Why should the "LF" path be active too in this condition?
And if the "LF" path is active to provide a baseline for this "normal" condition, the impact of the filter GD would show up, or do you think differently?
Why should the "HF" path be active too in this condition and what should it carry?
While it generally is a good consideration, any argument (haven't I asked that before?) why these experimental setup would skew the results is still missing.
Would be an easier experimental process but still does not invalidate the other approach, unless there are arguments.
I've to search, but have a faint memory that the experimenters in one of the follow ups later used 192/24, but a full range covering the whole audio band and in addition the ultrasonics up to 100 kHz?
There once was a fullrange prototype using plasma for everything but ....
I think Bill was referring to this...
No mention of direction of radial travel. Also the experiment is easy, put a stylus down on a blank LP.
Talking about preferred bit depth in recordings.
This recording (*) has a hefty 70 dB difference btn lowest and highest music level and if it was recorded without clipping it would have at least 3dB more.
Right at the beginning, during the first second, the fagotto changes from F to B#. Adjust the playback volume so that you can just perceive this change in note. This is the lowest music level. Now, listen the whole musical track at this volume setting.
What do you think, with the achievable dynamic range of the playback audio chain, the ambient noise level at your listening space and your highest allowed playback music level , would a higher bit depth recording be potentially advantageous?
