I'd say it's a pretty good start, perhaps enough for most people. High-end people are just a too loud minority :). Take a bit of time with the new system, listen to a lot of music, and you will get to learn and grow your own preferences in the process. Later you could get in mods (or get them done by someone else, as they do matter), or eventually change the amp and/or the headphones altogether, but you will need to spend multiple times your current expenditure if you want to seriously move up (e.g. Mjolnir Carbon + 007/009). The question is, will you really want to do this, or will you be left satisfied with this system. It depends on one's music preferences, listening culture and preferences etc. So just relax, enjoy the music at least for a year, and compare other options to this system. Imagine you'd have a much better system now: you'd still enjoy the same music :). So don't let that spoiled by the itching thought there are even better systems out there :).
