Sorry to bring up an old thread. They say everywhere that the new "i" in every Grado model names stands for improved : new driver and cable design, enhanced ventilated diaphragm and cup housing refinements... or at least they say on Wikipedia. Are there another other "improvements" to be listed?
What about SR325i's improvements? I know, radical new design for the cups, with more room in them for better sound (simply put), new drivers... and that's it? was the cable improved too?
And as for individuals made comparisons, all there is to extract and learn from this thread is that sr325is is more bassy and sometimes sibilant during the break-in first hours of usage (do that means they are more detailed? more or less resolution?), and that's it?
I'd be curious to know more, from people who tried both (and does not own any of them at the moment, a criteria to avoid subjectivity, because sr325 owner will most of the time say they prefer their own version model).
Because I just bought a pair of used sr325 and I decided to pick the golden ones for their unique (silver color is too common in non-wooden headphones world) look and the fact they're now discontinued (so they will become rarer to find, in the long run). Now I want to know what I'll be missing compared to if I would have bought the new shiny chromed "is", or will I really be missing anything?
