I agree with el-bo here that simple can be the best some times.. At least at the writing stage, you shouldn't think about how advanced and crazy this composition will be. That will most likely make you think it's a lot of work, and can put you off some times.
I have also gone through the same thing, and I think we all have at some point.
When it comes to gear, I've found out that I usually get more inspiration the less gear I use. That's why I now use two different studios, one project studio and one big recording/production/mixing studio.
If you sit in a room popped of smooth gear, it might kill your inspiration quite fast, as you will think about all the gear instead of how the music should sound like. I honestly think this is a trap most producers go into.
Of course, some things that have been mentioned several times before, such as going somewhere completely different, listening to your favourite music, talk with other producers, and don't think that you HAVE TO make something awesome. That stuff usually just comes by itself.
Good luck with your inspiration!
