PHONO CARTRIDGES

GRADO manufactures 4 series of phonograph cartridges.
They are, in decreasing price order:

- The STATEMENT series: 1 model
- The REFERENCE series: 4 models
-The PRESTIGE series: 6 models
-The SPECIALITE series: 6 models, 3 sub series: DJ, Mono and  78 tours.

All the GRAD0 cartridges work on the "FLUXBRIDGER" principle (see "Operational  principle’ for further details).
The STATEMENT and REFERENCE series are built in a very dense and exotic Australian wood : jarrah

The PRESTIGE and SPECIALITE series are made of black plastic.
 

The STATEMENT SERIES

The phonograph cartridges STATEMENT 1
It is an improved version of THE STATEMENT.

The improvements are: 

  • Optimized coils: less turns for a quicker response.
  • A better control of the internal resonances with the use of an anti resonant putty.
  • A substantial decrease of mass of the moving parts in order to further increase speed response.
  • The whole mechanism is fitted inside a solid piece of high density Australian wood called jarrah which is then filled with epoxy in order to have a better control of unwanted resonances.
Whoever was been impressed with THE STATEMENT series is in for a serious surprise upon listening to THE STATEMENT 1


 

GradoStatement1



 

GRADO takes charge…


After several years of research and an endless quest for perfection GRADO is proud to introduce its best phonograph cartridge: THE STATEMENT 1
The coils are made with gold wire, the cantilever/bushing out of boron and the diamond of a shape specific to GRADO.
Of course made by hand, the mechanism is buried in an epoxy filled solid piece of an extremely dense piece of Australian wood called jarrah. The output level is 0.75 mv, well suited for a low level phono input:  (MC).
The dynamic and bass extension are impressive. You will feel the “authority” of the cartridge. Typical of Grado, the mid range is rich, detailed and convincing. The upper band seems to never end, the speed is phenomenal; the all bandwidth is breathing finesse. The stereo image is precise and solid: you will be “pulled” into the music!


Michael Fremer simply said:
“It is the best cartridge I have ever heard, irrelevant of price”...
 Jonathan Valin of ’Absolute Sound uses it as a reference cartridge

How to identify a STATEMENT 1 : 2 letters are pyro-engraved on the top of the cartridge: GS means STATEMENT : 0.5mV.


The diamond (stylus) is not replaceable on wood “dressed” cartridges. When worn out take advantage of our offer to get a brand new cartridge at a reduced price. Please consult a GRADO dealer, we have an interesting "SECOND TIME BUYER" program.

The phonograph cartridges REFERENCE 1 and MASTER 1

The REFERENCE 1 and the MASTER 1 are a sub series; they have different diamonds: The diamond on the REFERENCE 1 is of a type called "nude elliptical" whereas the one on the MASTER 1 is ellipsoidal.

The cantilevers of this sub series have a masse about 5% inferior to the ones of the SONATA and PLATINUM, it is made of 5 tubes of different diameter in order to “break up” the transmission of vibrations of parasite origin. We call it “OTL” optimized transmission line.
The coils are made of oxygen free ‘’UHPLC’’ copper.
How to identify a REFERENCE 1 or MASTER 1 : 2 letters are pyro-engraved on the top of the cartridge,: 

RR : REFERENCE 1 Hi output
SR : REFERENCE 1 Low output
RM : MASTER 1 Hi output
SM : MASTER 1 Low output

GradoReference&Master1

 

The improvements made to the REFERENCE 1 and MASTER 1 compared to REFERENCE and MASTER are :

  • Optimization of the coils : less turns and less in this case means  better fidelity
  • A better control of the internal resonances with the use of an anti resonant putty
  • A substantial decrease of mass of the stylus cantilever assembly
  • The whole mechanism is fitted inside a solid piece of high density Australian wood called jarrah which is then filled with epoxy in order to have a better control of unwanted resonances.

REFERENCE 1 and MASTER 1 are available in 2 versions : 

Low level output : 0.5mV, suited for Moving coil input(MC).

High level output : 5mV, for moving magnet input

The diamond (stylus) is not replaceable on wood “dressed” cartridges.

The phonograph cartridges SONATA 1 and PLATINUM 1.

Here is another sub series in the Reference series: the SONATA 1 and PLATINUM 1
The SONATA is the most sophisticated of the 2. The “bodies” are identical but the diamonds (stylus) are different. A ‘’nude elliptical’’
diamond is fitted on the SONATA 1, the PLATINUM 1 receives an elliptical one.
The cantilever of this sub series has a mass about 10% inferior to the ones used in the PRESTIGE series. it is made of 4 tubes of different diameter in order to “break up” the transmission of vibrations of parasite origin. We call it “OTL” optimized transmission line.
The coils are made of oxygen free ‘’UHPLC’’ copper.

How to identify a SONATA 1 or a PLATINUM 1:
2 letters are pyro-engraved on the top of the
cartridge,: 

RS : SONATA 1 Hi output
SS : SONATA 1 Low output
RP : PLATINUM 1 Hi output
SP : PLATINUM 1 Low output

GradoSonata&Platinum1

 

The improvements made to the SONATA 1 et PLATINUM 1 compared to SONATA and MASTER are :

  • Optimization of the coils : less turns and less in this case means  better fidelity

  • A better control of the internal resonances with the use of an anti resonant putty

  • A substantial decrease of mass of the stylus cantilever assembly

  • The whole mechanism is fitted inside a solid piece of high density Australian wood called jarrah which is then filled with epoxy in order to have a better control of unwanted resonances.

SONATA 1 and PLATINUM 1 are available in 2 versions:

  • A better control of unwanted resonances
  • A substantial decrease in mass of the cantilever diamond assembly (moving parts)

    GradoSonata&Platinum1
  •  

    The models GOLD 1 SILVER 1 use a 4 piece cantilever, of ‘’OTL’’ type (optimized transmission line), attached to a brass bushing.
