The i-Grado use the SR60i drivers, and many say they have the qualities of the SR60i. (Presumably the e-Grado moved to the SR60e drivers.) The SR60i was an espcially good headphone. Up to you. I have the 225e but might get a pair of e-Grado for portable use. 

According to Grado's web site, the e-Grado do use the SR60e drivers.  I'm actually waiting on my e-Grado cans to come back from Grado Labs where I  sent them in for repair a couple of weeks ago.

In my opinion, this can be explain by sample to sample variations.

Have you compared your eGrado to the SR60e? I had both the SR60i and the iGrado but they were far apart in time so I can't tell how different they were. That said I really liked my iGrado.
 
@GreenBow: Think twice before using the eGrado for portable use. Comfort might be an issue and they leak sound like hell, so jogging or commuting with them might not be pleasant. I used my iGrado at the office as a cheap workplace Grado replacement for the big cans at home, and for that purpose I could not be happier. Poor isolation was not an issue at all, coz at least I could tell when the boss was calling me...

I in the meantime listen to the 225th with samsung s3 and I must say they feel just fine, I sent back a iBasso DX80 because the sound was too shrill and fatiguing

I just looked up the samsung s3 dac chip and I see it uses the Wolfson dac. I wonder if that's why you prefer the output of your samsung.  It's a shame that Wolfson seems to have fallen out of favor with DAC makers. 

 

[cirodts]

maybe I take a ak jr which also uses a Wolfson and andro well with grado

I have a sr225e the sound is a little cold because too many average, detail is good but not excellent, will improve with more hours of listening?
Until now asd I did a burn-in of more or less 60 hours.

The Astell & Kern Jr is What Hi-Fi winner of portable music player. 
 
Quite a few people though have started adding the Chord Mojo to their music player.

The sound on the 225e's is a bit "cold" - and detail is very good.
IMO they can't be beat overall at their price point.
 
But if your ears are demanding something better, you may have
to go up the ladder. First, though, I'd try a reasonably good
inexpensive amp such as the JDS Labs cMoy.
 
Personally, I think that further break-in may help, but it won't
change the fundamental characteristics of the headphones.

I also senn. hd 598, has a warmer sound and natural, but the 225 is more dynamic and direct sinned just a little bit his cool otherwise it would be perfect.
samsung s3 with Wolfson DAC however the 225 sounds great, after my bad experience with iBasso DX80 I try another dap.

cirodts,
 
Please take a look at this article...

specifically the photo with the caption "taped bowls"
 
If that doesn't fix the treble issue you are having then maybe the Grado 225 is not for you.
