The problem with vinyl is cartridge inadequacies
One major reason for my preference for 78s is the presence.
I can only achieve the quality that I strive for by playing a 78 slow.
What I hear when playing a stereo record is a sense of lack of mid-range
texture. I use a Shure M97 cartridge for slow dub 78s only. I find that the
sound is compressed when I play a 78 at full speed. This is due, I believe
to the flexing of the cantilever assembly in the cartridge. Less so than an
M44 which has a thicker and thus more rigid cantilever. On a 33 1/3 I hear
sibilants popping out at you with a washed-out quality of mid-range. The
location of the pick-up in many stereo cartridges is inside the body of the
cartridge. The vibrations relayed by the cantilever are accurate for bass -
i.e. the stylus can reach the peak of a wave form without flexing because
there is adequate time for it to achieve this. high frequencies are far
smaller and can be tracked adequately as well.
The problem is the mid-range frequencies - a cantilever assembly will flex
slightly, not reaching the full amplitude of the wave form. In the case of a
tuba, you will tend to hear the fundamental of the note which will overpower
the overtones which give the sound more character.
The General Electric VR22 - Golden Classic - variable reluctance cartridges
address this issue by working in an entirely different manner. The magnet is
on the very tip of the cantilever . The relationship of the magnet with the
two metal nodes that protrude from the cartridge induces magnetic
fluctuations which are picked up by two coils within the body of the
cartridge. The cantilever in this design is only a ground in the circuit and
does not need to be rigid in order to perform it's function.
As I was curious about this cartridge, I found a new-old stock 1960 Golden
Classic which I have mounted on a ca. 1935 Micro transcription turntable
with a professional Audax tone arm.
The following link is to comparative samples of Renata Tebaldi singing Un
Bel Di from London issue of Madame Butterfly. Original sample rate 96,000/24
resampled to 44,100/16. I ran a very low dehum filter to both and maximized
the levels for comparison (so at least the peaks are in line with each
other. As I expected, the GE golden classic retains more of the breath of
the voice and the strings have more presence.
I prefer the 58 year old cartridge on the 85 year old Micro(later McCurdy)
to the Shure on a Technics SP-15 -Mickey

It in’t so surprising to me that it is sourced from digital - there is no
economical way to record analog any more - the question is, has it been
damaged by poor digital practices?
