These Audio Sensibilities interconnects are worth a look. 7N copper and cryogenically treated. Price is in Canadian $ so a 7m pair should be within your budget in US$. They also have a cheaper XLR that’s about half the price of this one.

These Audio Envy interconnects have a good reputation and would also be well below your budget.

Probably can’t go too wrong with Mogami either. Best of luck.
