Tube AMP or SS

Hello everyone, I need some advice on an amp to purchase, maybe I dont even need one but need your expertise. I have a Yamaha rx-a1000 recv and MA S8 speakers and center, plus rears. I listen to jazz and watch now and them some blockbuster stuff. Looking to increase the clarity and sound stage. Dont have much cash, and was wondering if a tube amp would make a big difference. If so, can I purchase anything in the 1k range?
