Give it a while. These break in a lot more than an Ipod. I also didn't find it more insightful but still less ringy than my touch when new but now it just smokes it. I never really found them sounding the same as you are but at this point I do find the Rocco clearly better on IEMs where it was not a big deal with stock FW when new. The RoCoo always shows better drive capability for cans. Here's my comments from another thread.
I just received my 2nd RoCoo-p. I'm happy to report that I wasn't crazy regarding the sound and my original thoughts on FW. These clearly break in to a great player. This unit sounds just like my 1st did when new. It's a bit congested and lacks some top extension and detail. It made me long to get that top articulation that my run in player now displays extremely well with the stock FW.
If you'd like more top extension and ambient decay out of the box, just give it a while and I think you'll find it a wonderful device. I really have to say it sounds great as currently delivered (once run in) and has a nice sense of authority and control without any heavyhandedness while still having good note weight and plenty of detail.
