After spending several hours with the SR-80e it is clearly a high-performing bargain headphone. I can try to do some mental memory comparisons with my previous woody 225i (with some sort of grill mod too) but I don't think it would be fair because in addition I used the 225i with higher-end equipment. Based on my memory of iPhone usage, the 225 is bit more refined in regards to layering and imaging. Bass too was deeper and more impactful but maybe that was due to the wood cups? I also felt that there could have been more texture/palpability in the midrange. Notes are more rounded/smoother with the SR-80e and with the SR-225 the notes had a more distinct leading edge. Again, I am relying on memory
Upon early listening I felt the SR-80e was a slight hair off-tone, vocals and guitar strings didn't sound accurate. At the same time I wasn't liking the stock ear pads so I swapped them out with fresh Sennheiser HD414 yellow pads. Much better comfort and maybe it was just a bit of mental or mechanical burn-in but now everything sounds closer to what I expect tonally.
The SR-80 has all the features of the Grado sound. There is a distinctness to Grado headphones. There is little grain and the drivers have no issues keeping up with dynamic music. Music just flows from these things. I now know why people think Grados are great with rock and metal. It's effortless reproduction of those genres. I had the HD-800 at some point and I like that headphone. It also has the speed to keep up with the most dynamic of music, but it doesn't have the meat-around-the-bones sound like the Grados. If you want meat and potatoes then go Grado. If you want just the potato then go HD800

There's room for both headphones in this world.
I still have my eye on the prize, the PS500e. It will have some stiff competition because I am/was an ortho guy at heart, but I have time to decide.
As for mods on this SR-80e, what do you guys think? Quarter mod or go Cush? Anything else I should consider?
EDIT: Lots of threads on Grado mods. Most likely not going to get too deep into modding. Barely have enough time to listen with 6-month old twins, but if you have easy mods feel free to suggest. I can also enjoy them as is. Nothing wrong in that either.
