(The Sonata is also known as the Signature.)
The Platinum and Sonata models use a modified four piece OTL cantilever technology achieving a 10% tip mass reduction over the Prestige series and ultra-high purity long crystal (UHPLC) oxygen free copper wire in the coils. The Platinum model uses Grado's specially designed elliptical diamond mounted on a brass bushing, and the Sonata model uses Grado's specially designed nude elliptical diamond.
What People are saying about the Sonata...
| "The Sonata is a refined and dynamic cartridge. It offers performance ahead of what you might expect for the price. Above all, the Sonata encourages you to play more of your LPs – and what greater recommendation can there be?" Michael Jones / AudioEnz |
| "I'd go so far as to say that the Sonata reminded me more of my Koetsu Urishi ($4000) then of my 8MZ." |
| "No cartridge reproduces a female voice better than this." |
| "For the extra money, the Reference Sonata represents a leap of performance beyond the Platinum and hints at what an expensive moving coil can do." |
| Stereophile / Robert Reina Vol.21, No.6 |
| "After a week of warm-up, during which the Sonata was most notable for the solidity of its bass and power of itŐs subsonic bass, the sound started to become very musical." Andrew Marshall / Audio Ideas Guide / Canada |

Stereophile Vol.23, No.12
| "The
Grado Reference Platinum phono cartridge is the most musical cartridge
I've ever heard, period!" Audio Adventure / Dayna B Vol.4, No.1 |
| "At
the level of investment that brings you a Reference Platinum,
the performance is a amazing!" Primyl Vinyl Exchange / Bruce Kennett |
| "If
this is the bottom of the range, then what does the flagship model
offer?" HiFi News / Ken Kessler |
| "On
Antel Dorati's interpretation of Stravinsky's Firebird, the Platinum's
reproduction of room sound and image dimensionality gave a vibrant
sense of realism to the work." Stereophile / Robert Reina Vol.21, No.6 |
| "A
prime advantage/disadvantage of phono reproduction is that every cartridge
sounds different. Choosing one is like selecting wine, a process easy
to get lost in. But if the cartridge is good enough, like Grado's
Platinum, you'll get lost in the music." Audio / Ivan Berger Vol.82, No. 2 |
| "Let
me say straight out: like the Maggie 1.6QRs or the Goldman SRA, the
Grado Platinum is one of those incredible bargains that doesn't
just give you a "taste" of high fidelity but pretty much the whole
enchilada for the price of, er, a whole enchilada" Fi magazine / Jonathan Valin Vol.3, No.11 |
