Variations Between Grado Headphone Models
 
From the entry level iGrado to the Top-of-the-Line PS1000 the entire Grado headphone line is worthy of being called true audiophile sound quality.  There is a consistency of sound throughout the line from top down.
The following list will provide a simple comparison to step you through the top features that separate the different models.
 
iGrado Series
iGrado: Grado’s version of a portable knock-around headphone. Perfect for use with all portable devices. The headphone housing is designed by Grado but manufactured in China. Grado sends their SR60 drivers to China and has the headphones assembled there thus enabling an economically produced headphone unrivaled at its price.
Sound: good bass, good resolution and smooth sound.

Prestige Series
SR60i: This headphone has gained “LEGENDARY” status. The SR60 has received rave reviews from around the world and is the most commonly recommended headphone on the market today. The SR60 was the Stereophile’s “PRODUCT OF THE YEAR” in two categories, “The Accessory of Year” and the more prestigious “Budget Component of Year”.
Sound: good bass, excellent resolution, very smooth sound.
 
SR80i: This headphone has all the attributes of the SR60 with improved response.  The SR80 is the winner of the “GOLDEN NOTE AWARD” presented by the Academy For The Advancement Of High End Audio, and has received Audio Video’s “HI-FI GRAND PRIX AWARD”.

.

SR225i: This headphone has closer matched drivers and an improved rear screen that increases airflow by 50%.
Sound: Closer driver tolerances helps enlarged the sound stage while the more open rear screen helps free the headphones of colorations. The SR225i offers excellent value for the dollar like all Grado headphones.
 
SR325is: The top of the line in the Grado Prestige Series.  Winner of Audio Video’s “HI-FI GRAND PRIX AWARD”.
Sound: The SR325is embodies all the sound benefits of the Signature series, clean open highs, smooth well defined midrange and bass that will rock. The SR325is is an excellent value yielding performance that one would have to spend 3-4 times their price in competing headphones.
 
Reference Series
RS2i: The RS2i features handcrafted mahogany earpieces that require an intricate curing process to optimize the tonal quality.  The RS2i keeps a very close family resemblance in looks and sound to its big brother the RS1i.
Sound: warm, smooth, full-bodied, rich and non-fatiguing...just like its older sibling.
RS1i: Considered by serious headphone users as one of the best headphones available in the world.  Top listed headphone on Stereophile’s Class A “Recommended Components” category.

The presentation is very detailed, the bass is deep and the music is very tight and non-fatiguing. All with a soundstage that is huge allowing for unbelievable separation and layering of the music which is simply stunning.
A must for serious music lovers.
