The Grado Sonata & Platinum
(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."

and about the Platinum...
Nominated for Analog Source
"PRODUCT OF THE YEAR" award.
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"
