Always wondered who actually had to listed to all 4 sides whilst it was being cut. I did try once, but only managed about 10 minutes. I think Ben Duncan put me off audio writers trying to be funny for life!
Well it fits on 1 CD for double CD try to get through https://en.wikipedia.org/wiki/Batztoutai_with_Material_Gadgets. I could supply you of course. 😀 BTW when I'm set up again I do intend to make you a copy of that Morricone LP so you can judge my low-brow LP setup. 😉

Yup, even the choice of Metal Machine Music is surely tongue in cheek........ I think the article is well crafted, a fun jibe at the writing genre and a repost to the technocrats that almost sneaks under the radar !

Modest I. Predlozheniye = "A modest proposal", Jonathan Swift on the Irish question, 1729 = po-faced satire. Heh heh heh ... the chuckles started on the first line and kept coming.
Amh Ulchach is sort of Scots Gaelic for smart-**** kid, Glenghniomhaid rolls off the tongue as "Glen home-made", doaty baws are dirty balls, not to mention my cousin bum-less and the TRASHING of the sacred canon of recorded music.
I just WISH Modest was a regular contributor ...
By the way, the tartan of clan McNab has marvellous damping properties, and would be a fine match for that solid austenitic cantilever with integrated stylus.

I had a friend from the McNabs his grandfather bought him an entire cask of McCallans as a birth gift to be held at the distillery until requested. Last I heard he has left it for over 40yrs now probably worth $400,000 if bottled. Buying a newborn a cask of whiskey has to be in the right spirit.

Yup, it's like a cryptic crossword. It took me ages to get "my old engineer friend Dr. Farquar Kentigern MacBhreatnaich"
Very funny 🙂

just a couple of interesting links ..
Shellac/vinyl resonance

I knew a couple of people who would dispute his view of the LEAK pickup but the improved version was never put into production.

Not sure I understand his point on the compliance of shellac vs vinyl.
Really doesn't make sense to me.

the material is more or less pliable by the stylus ,riding on the track containing high frequency info
The fundamental physics is that whenever you combine mass and springiness/compliance, you get a mechanical resonance.
The resonance frequency is always of the form {constant x [square_root_of(springiness/mass)]}
There are two unavoidable mechanical resonances in a record player cartridge / arm / record combination, caused by two different masses, and two different compliances, in the system.
At the low frequency end, there is the resonance created by the compliance of the stylus, and the effective mass of the entire tone arm. This is usually placed somewhere below 20 Hz (often much lower), to allow response to the lowest bass frequencies in the audio band.
At the high frequency end, there is the resonance created by the tiny mass of the jewel at the stylus tip, and the compliance of the material of the record itself. This sets the upper frequency limit of that cartridge playing that record. Ideally above 20 kHz (much higher since the era of the quadraphonic record drove the rapid evolution of extremely low tip-mass playback cartridges.)
The claim here is that shellac has much less compliance than vinyl, and therefore will produce a higher upper resonance frequency, all else being equal.
I have my doubts about the "all else being equal" part. Weren't the grooves in shellac records much larger than the later vinyl LP microgroove, meaning larger contact area between stylus tip and record wall? Weren't the stylus tips themselves larger and heavier? This is not an apples-to-apples comparison.

bondini I saw what you wrote about theory and practice and I just thought I'd share my favorite quote of a German proverb that Gilbert Briggs (Wharfedale) has in one of his books.
"When theory and practice agree both are wrong".
It sounds better in the German ha ha.

Any news ?
Are there measurements concerning S/N ratio of RIAA phono preamps and record surface noise at the same time ?
The information like
Pass Aleph Ono phono preamplifier:
Unweighted S/N ratio: 90dB ref. 10mV input (MM), 81dB ref. 1mV input (MC)
Linn Linto:
A-weighted S/N ratio (ref. 500uV input at 1kHz) 85.3dB
Graham Audio Era Gold Mk.V phono stage:
Output noise (A wtd): –75dB
usually found are completely useless in real life because a RIAA phono pre-amp isn't a microphone preamp and is never operated without a record on a running turntable and the cartridge-needle lowered.
read also last post under
Shunt feedback in phono preamplifiers : new topics on this forum
What a strange idea, a phono preamp that cleans up the Surface noise of an LP.
And that should be done with the thermal noise from the 47K input resistor ?
I think this is confused with a “cooled” resistor topology where a few dB in S/N can be gained, not from the LP surface noise but from the phono amp’s noise.
However since the noise of modern phono amps is below auditory treshold and LP Surface noise is at least 20dB much lower, are two reasons why increasing the phono amp’s S/N makes no sense.

Hi...
You wrote: "... want to know all approaches ..."
Maybe it's not the kind of approach you meant, but did you see that? (same in german)
There you hardly hear anything of the surface noise of a record.

Hmmm I struggle with understanding this. Surely dragging a rock across a flatish surface follows mostly a flicker noise law? And that is notoriously random....unless one can work on factors that influence it....which aren't electronic...

I remember Dolby NR system for reducing tape hiss noise. A lot of records were made using this system. I hate those records for annoying hiss in the pauses. This is exactly the case where cure is worse than malady.
Yes, because this only applies to associated CX-encoded vinyl records. Most exist records are without so called "Compatible Expansion"
I am looking for commercial RIAA MM preamp devices, which operates in shunt feedback mode according the description in last posting under
Shunt feedback in phono preamplifiers - audio qualia
Maybe yes, maybe no. I don't but I want to know. Therefore the desire to find a commercial available device (haven't time to realize a diy project in this kind).
