Vintage you may find a lot of decent amps for that price, hundreds, you have to decide and to know what are you looking for and what is more important for you, any will drive pretty good the Axioms, I would suggest to get a Pioneer SA xx00 series from the 70's 80's, I like that Pioneer sound, the bigger the number the better and more powerful, and more features you may find....do a search in EBay, you may find a lot of good amps there, a Sansui, or maybe a Kenwood.....Any will sound better than nowadays plastic toys for around that price....
