some old posts from http://headphiles.org about the SR325is :)

===

the 3rd version of Grado 325 ==> 325is





...

initial impression:
Grado 1/4 to 1/8 adaptor has same diameter cable as MS2i but Grado 325is has much thicker cables ... there seem to be an increased volume of the internal chamber of 325is

less than 3 hours of "burn in"
mids&highs on the revealing side which i always prefer... highs are not too bright nor offensive to my ears...

laptop (itunes lossless) ==> kimber usb cable ==> 707DAC ==> GW TW-J9 ==> Grado 325is

through my ears i was able to A/B kimber vs ordinary usb cable ==> kimber wins...  mids&highs went up.. there was also perceived bass bump... will see if it was only volume (loudness) that has improved.. but the change was on the positive side ...kindly please consider i am not a usual cable believer  ;)

will update this thread as i do the routine ;)

cheers !!!
fer

6th hour burn in

took off my GW TW-J9 amp... i was able to power up boss Ken's Musical Fidelity X-CANS amp... hooked to the rest... 325is now on Grado flats

low level volume... i can say bass is ample and well controlled... mids has aggressiveness boss Ken & i prefer... highs still not too bright

thick cables shorter by around 10 inches compared to cables of MS1 & MS2i



4 hours on this metal Grado (fitted with comfy pads) ... playing very fast music with dynamic passages... Ibasso D2 on low gain setting powering it enough... darn, no listener fatigue... fast attacking notes, deep bass rumbling... accuracy is the name of the game... will look for time to give Grado 325iS update mini impression  ;)

Steely Dan, Madonna, Ted Howe, Acoustic Alchemy, Yanni, Basia, Sade, et al ... wow !!!

I'll echo Fer's sentiments...the 325is with comfy pads alleviates the fatigue with only a miniscule loss of detail. Abrasive, underproduced black metal is now listenable on them hehehe. Everything is still clear and punchy! :)

after almost 3 weeks of sleep i pulled sr325iS and hooked it on my s/s headphone amp ... G&W TW-J9 is my "big E5" as it has bass boost ON/OFF switch too

source: laptop with iTunes lossless files ripped from CDs

G&W bass boost ON, volume between 8:00 to 9:00
sr325iS attack fast notes... i can feel guitarists shifting to various music notes.. bass slum ample and delivered with good control... piano primary notes and reverberation appreciated.. fast drums detailed with metal cymbals sounding very natural ... aggressiveness on mids unfold with much pleasing revelation which is very good for vocals & midrange notes... deep cavernous LF octave when present .. soundspread beyond both drivers... this is the usual Grado signature i am familiar with and sr325iS is one very good sample
...

very similar [sr325is vs. ms2i]... as per my ears and music, ms2i wins on LF while sr325iS on mids.. difference too small that you may only appreciate through numerous repeat A/B comparo

after all, these are twins  8)

Musical Examples
On Alison Krauss and Union Station’s song  “Stay” [Alison Krauss & Union Station – Forget About It, Rounder], Alison’s violin has a superb sense of body, overtones and string/bow texture. Kim Kashkashian’s viola on “Three Arias” from Neharot [ECM] is similarly well balanced and clear.

Going back to “Stay”, Alison’s voice, which is rather light, occasionally gets into a range where there is some slightly sibilant stridency from the 325s. Fortunately, this is low enough in level that it isn’t too distracting, something I can’t always say competing headphones.

Later on Forget About It, the song “Maybe” has a solo bass drum whack that is startlingly powerful and well defined on the 325s. This is, given the air pressure limitations of headphones, a rendition that sounds very much like what one hears from a bass drum in a concert hall. I commented on this same drum when I reviewed the Ultrasone Edition 8s. The Grados, at 1/5 the price have a little less bass power and depth, but better definition than the Ultrasones, which is high praise indeed.

On Brandi Carlile’s song “The Story”, from the album of the same name[Columbia], we get to see how well the 325s hold up with power pop. The impressive thing here is that with drums, guitars (acoustic and electric), bass, and vocals going full tilt, we still can hear each instrument distinctly.

...

Bottom Line:
Grado’s SR325is is a transparent headphone that seems to have been voiced by musicians. This headphone will make you think very hard about why you would spend more, particularly if musical accuracy is your goal and if frequency extension isn’t at the top of your list of needs.

    Sonic Character

    The thing that immediately strikes you about the 325 is the clarity and smoothness of the midrange. For those not raised from birth on audiophile Kool-Aid, I should be clear that this observation carries more weight than might be readily apparent. The fundamental tones of most instruments are in the mid-range. Get the mid-range right, and you’re 80% of the way home. As easy as the sentence is to write, I should also be clear that it isn’t that easy to do. Check out my Sennheiser HD800 review for a discussion of a high-end headphone that struggles just slightly in this area. And, yes, I am saying you can validly compare and cross shop the SR325is and the HD800 (assuming your goal is musical accuracy).

    The mid-range clarity of the SR325is shows up in its’ natural portrayal of the tonality and timbres of individual instruments. When we think of tonal balance in an audio product, we sometimes mean that overall bass/midrange/treble evenness that allows a band or orchestra to sound right. But it is also very important for audio products to render the distinctive, “signature” voices of individual instruments well. This latter idea is a critical test of smooth and balanced midrange, because that’s where most instruments produce sound.

    Take the voice of an acoustic guitar as an example

    . At times this may simply be a matter of the 325s revealing quite well what is on the recording, but sometimes there is a slight peakiness to the sound. Still the 325s sound both better balanced and less uneven that the Sennheiser HD 650s or the Denon AH-D5000s, both very good headphones that sell for nearly twice the Grado’s price.

    Competitive Comparisons

    The Grado SR325is merits comparison with a wide range of headphones. Here are a few samples to give you an idea of how competitive we found the 325 to be:

        * When you step up from the SR60i to the SR325i, you get a more refined version of the Grado sound, with deeper bass and a smoother mid-range and treble presentation.
        * The highly regarded Shure SRH840 provides a closer price point alternative. The Shures seem more extended in the bass and about as well balanced, but lack the “Nth” degree of transparency and openness of the Grados.
        * The Sennheiser HD 650 is more costly than the Grados. It has a warmer sound, which I would view as less accurate, and also has less transparency and smoothness when compared with the SR325is. The Sennheisers could be considered more polite and forgiving.

Sexy? Oh yes.


yup, I agree, the sr325is is a sexy can :D

... sorry for the crappy pic ...

Really aggressive and wild cans. Great contrast to the DT880/K701 sound sigs!

Not recommended for high volume listening though, as they can get brighter than the sun on some tracks. Great for acoustic guitars and light rock, I think they'd do great with tubes, which can tame their wild spirit a bit.

I'm eyeing OJ's LD MKIII, I think they'd be great with the 325is
