I've been slowly writing one. The problem is I end up writing two reviews: One a few pages with a long story explaining what I think of them and the reasons why, along with a lot of background about my understanding of audio. The other review is 3 lines and is really all you need if you don't need the drivel of the other one.

How about the short review as a pre-lude to the much anticipated full review?

Ive seen several posts about the magnums being heavier than the 325.  Does anyone know the exact change in weight?  Or what about hazarding a guess?

I just sent in an older pair of 325i over to Symphones for modding (chose the magnum light option). I've been a big fan of the John Grado sound for a while but I also really liked my HD800 when I had them. Figured I should give this more neutral Magnum driver a shot after reading so many positive comments.
 
And if i like the sound enough, I may opt for the gimbals upgrade next year to add a bit more class to the setup :)
 
I should have the magnums back in my possession in a couple weeks. I'm really looking forward to it.

i loved them even w/o the burn in, which has only enhanced their sound.

Save your money. No point taking a step back. Spend it on a good source.
The Magnum does everything well. But in particular.. to me.. is how realistically hi-hat and cymbals sound. I find that is what most headphones fail to reproduce well. The new "high-end" Grados are un-listenable to me because they fail so miserably at reproducing those sounds.

I agree with you 100%, hi-hat and cymbals are outstanding with my Magnum V4 !

I did my first 10+ hrs with bowls.
I just switched to flats. There is pretty much no soundstage and I really don't care. There is exactly how much is mixed/mastered into the song. I'm really fine with that, some positioning.
 
The music is immersive, and I think I'm pretty much done looking, I've found my soulmate...for now.
 
I really don't know that I've got any more of a review in me, this is just "it".

with the flat´s the soundstage is not big but i think that the sound is more real with many more details
