Find something 9awg or 10awg. At the $200-$250 price point, I don't know that any two 9awg cords are going to sound appreciably different, but the large gauge will likely make a nice improvement on the amplifier versus the stock cord or a small 12awg cord. Off the top of my head, I can think of the VH Audio Flavor 4 and the Kimber PK10 Gold (both purchased used). I'm certain there are others.
I use a Purist Audio Dominus Ferrox on my 150A Reference amps, but it is considerably more than $250.
