I've been using a 125i for hundreds of hours and I love it. Recently I wanted to have an upgrade by getting a RS1i, but it turned out to be, how should I put it, not as good. Now I mean I still think it's a better sound, just not worth the price-sound ratio to me. So I tried the G cushion, but that made the RS1i overly bright. This is most obvious in rock/metal music. I am not exactly sure which version of RS1i I got, so here's a pic for you to see. If RS1i is supposed to sound like that, which one would be a direct upgrade from 125i? GS1000i? PS500? I would sell the RS1i if those are better for me.
