В чем разница между головками Grado MONO MC + и ME +?

https://respectphono.de/fr/grado-mc-cartridge-fr.html как видно что стилусы разные

Frequency Response: 10-50

Principal: MI

Imput Load: 47K

Output at 1KHz 5CM/sec.: 5mV

Recommended Tracking Force: 1.5

Stylus Type - MC+: E

Stylus Type - ME+: E

Inductance: 45mH

В каком месте?

Скорее уж в этом дело : The ME+ uses one of GRADO's upgraded generating systems.(ME+ использует одну из модернизированных генерирующих систем GRADO.)

The Prestige model MC+ uses a three-piece OTL cantilever technology, oxygen free wire in the coils and a specially designed, high polished elliptical diamond mounted in a brass bushing.

В престижной модели MC+ используется консольная технология OTL, состоящая из трех частей, бескислородная проволока в катушках и специально разработанный эллиптический бриллиант высокой полировки, установленный в латунной втулке

Иииии?

"Иииии?"-думаю что разница между ними мизерная...и она в нюансах

Я читал, конечно, эти описания. Буква E в типах стилуса и там, и сям обозначает эллиптическую заточку. Разница, возможно, и мизерная, но она составляет 60% стоимости. Очень хочется понять, в чем (на практике) она выражается.

OPTIMIZED TRANSMISSION LINE (OTL) STYLUS/CANTILEVER
Grado's OTL provides an ideal transfer of the signal from point to point, e.g., stylus to cantilever to magnet to coils, etc. This has been achieved by eliminating resonance at each of these key junctions. The transmission line cantilever consists of separate sections that are telescoped into each other. All sections are made of different alloys, some sections hollow, other sections solid. These sections are bonded together with materials that act as dampers, and are coated with a black proprietary material which controls and absorbs resonances that travel on the surface of the cantilever (known as skin effects). The OTL stylus/cantilever design will make your records sound quieter, improve the height, width, and depth of the soundstage, and offer more detail than previously obtainable. Cartridge Holography does exist...and that is what GradoÕs OTL technology is all about, more performance

PIVOTED FIXED AXIAL CANTILEVER STYLUS-GENERATOR
This design feature is basically quite simple. The "OTL" cantilever shaft is brought to a fixed axial pivot that supports the entire cantilever assembly. A miniature element attached to the end of the cantilever is allowed to move freely within the lines of flux of a stationary magnet and coil structure.


This system of support is mechanically more accurate (more linear) than conventional "teeter-totter" designs that utilize an iron armature to balance the mass of the cantilever. The teeter-totter design is supported in the center with a rubber donut mounting.

The fixed axial design has a very low tip mass, which results in lower distortion, improved transient response, and longer record life.

Description

There are many analog lovers with record collections that include mono albums.  Grado strive to have products that will fit all the needs of the analog enthusiast. So now, Grado offers two new cartridge models in a mono version.

The MC+ and the ME+ are mounted with an elliciptical diamond. The ME+ uses one of GRADO's upgraded generating systems. All wooden body cartridges are available in mono version. This will make your records quieter and enhance the musical pleasure of these recordings.

A miniature element attached to the end of the cantilever is allowed to move freely within the lines of flux of a stationary magnet and coil structure. This system of support is mechanically more accurate (more linear) than conventional "teeter-totter" designs that utilize an iron armature to balance the mass of the cantilever.

The fixed axial design has a very low tip mass, which results in lower distortion, improved transient response, and longer record life.

Flux-Bridger Generator

The Flux-Bridger design uses four separate magnetic gaps that the miniature element of the cantilever bridges. The miniature element moves between opposing flux gaps creating an increase in flux in one gap while reducing it in the other. The four separate magnetic gaps create a highly efficient and perfectly balanced system. This design requires fewer coil turns than conventional designs.

100% Quality Control

Each individual cartridge manufactured by Grado is hand assembled and tested for frequency response, channel output, channel balance, phase linearity, inductance and resistance. This meticulous care in design and construction lavished on each Grado cartridge contributes to an unchallenged consistency of performance and guarantee of reliability.

Prestige Series

The Prestige series of cartridges are designed for high output and excellent stability under severe use. A considerable tip mass reduction results in a frequency response to 50 kHz and beyond and tracking forces from 1-2 grams. They are acclaimed by experts as virtually the finest pickups in the world at their price. All styli in the Prestige series are user replaceable.

Зачем?..

Да, это единственное отличие, которое я видел с самого начала. Еще и градовцы в плане обратной связи жутко ленивые. Написал им еще в пятницу, ответа нет. Если вдруг ответят, обязательно отпишусь. Хотя наверняка, там будет нечто метафизическое.

Делюсь.
Мои вопросы - и их ответы.

Q: What is the main difference between your MC+ and ME+ cartridges? If I understand correctly, they have the same 5mV output.
A: the ME+ has a better performing generator, more transparency and dynamics
Q: Do they have stereo-sized needles (0.7 mm) or 1.0 mm?
A:  they have elliptical diamonds .3x.7

Только вот последний ответ я не очень понял. Радиус закругления 0.7 мм, а ".3" - это что?

эллиптическая заточка иглы 0.3*0.7мил

эллипс имеет два параметра.

Да, ну я и предполагал, что-то такое услышать) Градо вообще любит напустить эзотерики))

не 0.7мм а 0.7мил. один мил это одна тысячная доля дюйма=25,4мкм

да, конечно. Спасибо.
