It's like everything else, man. Most people who hate Grado do so because other's hate them. They're actually an extraordinarily well-respected headphone. Me- I enjoy the hate! I know better, and most of the people I truly respect do as well.
The 60e is a stunningly good headphone.
But- the 400i does trounce them in significant ways, especially in bass and smooth transition across the spectrum. I don't have to hate Grado to love the 400i, or the Primes for that matter.
Here's the thing, even dealers here is condescending towards them. And there's only 4 major dealers in the whole country.
Dealer said "oh... you come from sr60?" cue condescension tone, "yeah, i like them a lot, any advice on something $300 that can replicate and better-ize the sr60?", dealer said "grado sr60 is not real headphone".
I got that from 3 out of the 4 major dealers manager, the last store manager doesn't like comparing stuffs their store doesnt' sell and ask me to just try stuff out. That was... 1.5 years ago i guess, when i was finally in a position to upgrade to a $300 or so headphones from the old sr60...
So yeah, that's a widespread attitude. Which i'm guessing due to grado's lack of bass and shrill trebles. (Their opinions, not mine). But as you probably see my posts on Grado Fan Club, there's an official new Grado Dealer now where i live. Yeay. and they're pretty nice. No rs2e demo and expensive, but at least there's grado dealer here now.
Check out this document below... I found this from another head-fi thread some time ago. This person wrote a documents about almost all brands flagships and measured them.

Praised him for putting that much effort, but read their conclusion on Grado's flagship. Essentially saying how bad ps1000 is, and also mention sr60i in the same paragraph. I know by our ears Grado isn't a flawed headphone, and i've read somewhere from google that they design the headphone by ears, well that certainly works for them.
I like my sr325e.
I like the Alpha Dogs too. the only reason i didn't get them and opt for he-400i instead was due to my condition. Frequency response wise, if i have to choose one of the two due to wallet constraints, i'd naturally prefer the AD.
