Help with tube amps

I have recently become quite interested in puying a tube amp. I have no knowledge about tube amps but have been told of the magical sound a tube amp will make. I am looking to be able to put this tube amp into my system once in a while in order to experience this magic with my husband through a night of romantic acoustics every once in a while. Although my budget may seem low ($1000), I am hoping that there are some amps out there that will suit my needs. Amps I have looked at so far: Houston GSP-02, Sonic Frontiers SFS-80, and Decware Zen triode. Looking for any other suggestions and/or advice.
