I’m afraid at a $1000 budget you may be doomed to failure. Not only because of the amp, but also because you apparently also need a preamp — do not neglect the importance of the preamp. Your most cost-effective option is probably an integrated amp. Here’s a Plinius — it puts out 120Wpc into 8 Ohms and I can’t find its output into 4 Ohms, but Plinius amps tend to have pretty robust power supplies so it’s probably close to double the power down there, which should be adequate.

FWIW, and best of luck.
