Wouldn´t it be better to explain why that should be "plain BS" ?
Without it looks just like a matter of animosity. 😕
Although - due to Gibbs - the CD systems rise time is less than it ought to be, but an analog system with much higher bandwidth will have most likely a shorter rise time.
+1
For the CD, the rise time will depend on the kind of anti aliasing filters used (oversampling, delta sigma) ?

No I didn't have that! But SY tells me it is equivalent to the 6BK4 and I do have the data sheet for that.
Thanks,

Yeah that was 1979, as I said, the ortofon golden ears didn't decide the 20kHz lift was preferable until 1988. I may mod my Rondo to remove that one day.
I made a point of just stating without any justification, because the post I replied to was BS without any justification. Interesting the double standard applied.

If you can't be ar5ed to google then I am not spoon feeding you information.
I looked at the 17DIII measurements and it looks to be just average on tracking and high on HD. Based on the review John posted both Audio Technica MM and MC lines will cream it. You clearly like it and that is good, but I see no amazing superiority. Mind you very little in high end vinyl reply has any basis in Engineering reality* and is more bling and good back story.
*Note that £1000 for a new 17D3, whilst 2x the max I would pay for a cartridge is not silly compared to much out there and I also consider the JC-3+ to be pricey, but good engineering.
No double standard, as I see the things. JC's post (that you can agree or not) was about pure technical issues, your answer, as often, was a personal attack. Don't you feel the difference ?
Sorry, but it seems that you missed the last sentence of my post:
"Although - due to Gibbs - the CD systems rise time is less than it ought to be, but an analog system with much higher bandwidth will have most likely a shorter rise time."
I think in there is the justification embbeded for JC´s assertion, which i assume to be common knowledge (a system with a higher bandwidth usually has shorter rise time), therefore my imo polite question.
Maybe you could reconsider your "double standard theory" .....
You are looking for a HV regulator for color TV HV output it seems. Once really common. It will definitely handle the voltage since rated for 24 KV. Do check for x-rays.
Very kind of you to provide justification for JC's post, which he either could not or did not want to.
I wish I had a groupie like that! ;-)

Not really. I can spout the greatest nonsense without any justification as a 'technical post' . So?

Jan,
Why not register here and get the 6792 datasheet (bottom right hand corner) ?
Then you know for sure.

Lord, do you think we, poor sinners, will be worthy to receive your tablets of the law, one of theses days ?
As an agnostic,, I don' see any "greatest nonsense" to pretend that an analog system with a bandwidth of 20KHz (and usually a slow slope after this point) has a faster "rise time" than a digital system with a brick-wall AA filter at 20KHz ?

I don't know, it seems to have shortened the rise-to-the-occasion time quite a bit.

Look everybody, we are not writing technical papers here, we are discussing technical and subjective topics.
Now, my assertion is that CD will always be compromised compared to the BEST analog sources. I think we have proven it with direct listening tests.
The most obvious limitation of CD's is their sampling rate. I stated it in print, almost 40 years ago, that the sampling rate was just too low! Reality hasn't changed since before CD's were first introduced.
Now, every sort of audio system is compromised at the high frequency end.
Earlier MM phono cartridges in the Shure, Empire, Stanton family from the 60's barely could reach 20KHz, (usually less) AND they did it by a 4 pole resonance (2 poles electrical [inductance, capacitance, 47K resistance) and the mechanical resonance of the effective stylus tip mass resonating with the vinyl record. Back in the late 60's some phono cartridge manufacturers concentrated on lowering the effective tip mass to resonate significantly above 20KHz, and got better performance from it. The MC cartridge had been developed even earlier, and because their effective tip mass was lower than typical, Ortofon made an extended frequency cartridge, very early on, perhaps in the '50's.
Now what do we gain with MC cartridges compared to MM cartridges? Extended bandwidth, out to 40KHz or more, and then a 2 pole roll-off, not a 4 pole roll-off, that tends to preserve the transient response more accurately. So, if you use a quality MC cartridge, you make the rise-time of about 10us, whereas the MM cartridge, will rarely achieve this.
However, MM is still better than CD, because of the chosen sample rate of 44KHz, which was made to just make the CD work with video recorders at the time. Now we are stuck with the CD standard, and no matter how you work it, the high frequency transients will be compromised.
Now, that 96K+ is available, this problem has been solved, and 10us rise-time can be met, with SACD and DVD. Is this enough? So far not good enough for me, but then let's continue to improve things, probably more with the analog electronics connected to the digital chip, than with significant improvements with the digital chip itself. At least that is what my colleagues think.

But, what if the analogue system starts as vinyl? What rise time can it manage then? Ie, is the limiting factor what can be cut into the grooves....
Then we are two, it seems like my posts also vanish into thin air after a few hours.😕

Complete BS.
Specially to satisfy Jakob2 and Tournesol: I have published blind tests that show that people liked vinyl when they THOUGHT they were listening to vinyl, even when it was actually digital. The same test showed that people didn't like what they THOUGHT was digital, even when in reality they were listening to vinyl.
