For under $100 I say try out the Belkin PureAV Silver OCC 14AWG Speaker Cables. I've used these cables with tube amplification as well as solid state amplification and they sounded really nice.
For under $300 try Morrow Audio SP3 speaker wires. Often on the Morrow Audio website they come up for sale used and there are times when the have a sale and you can get an additional 10-20% off. I used the Morrow Audio SP3 speaker wires more the my tube amps though.
