As LarryAce said, it is probably not the setup - or the setup is just a small part of your boredom. Sure, sometimes we get inspired by playing other peoples sets. Just like it is fun to drive some else's car.
Do you take lessons? That is something that can inspire you greatly. And I am not saying this as a teacher. I am saying this as a student. There have been many times that I felt like I was just coasting. Not getting better, but not worse either. I would schedule a lesson with a great drummer and all of a sudden my outlook changed. It is a psychological change. It gives you hope and make's you look at things from another person's perspective.
If you are taking lessons and just working on rock, try to see if your teacher can give you some other styles. It is challenging to get the coordination right for latin, bossa nova's, jazz, etc... As you learn those styles, you will also be inspired by great players of the genres.
As stated by some others, try to get out and play. This is where you gain experience and apply what you are practicing at home and in lessons. If, until now, you have only played drumset, go out and find other performing opportunities. Most areas, no matter how small, have community bands which play concerts and parades. In fact I just saw one on the Fourth of July that played as the fireworks were going off. You will get a chance to play snare drum, bass drum, auxillary percussion, and even mallet percussion if you have experience with that. You may also play parades. I used to play parades and focus on my technique. And I got paid for it.
Go out and see other bands. You will be surprised at what you will pick up from other drummers. When we did the battle of the bands at the SF Jazz festival with the Tommy Dorsey Orchestra, I was set up right next to Rudy, the Dorsey drummer. I picked up a lot of stuff just by sitting there and watching him. And on the pieces where both bands played together, I still adapted what I played to fit what he was playing. It was definitely a learning experience. And we talked alot, before and after the gig. There is something inspiring about meeting other drummers and finding out what they do both in practice and with bands.
