Canare Digiflex Gold (some now for sale on Audiogon) gives you true 75-ohm connection and is well-built for low price. Whether it will represent an improvement over your current cable, I don't know.
An almost certain improvement, but beyond your $75 limit, is Kimber Illuminati D-60, which shows up used on Audiogon occasionally. But what's the rest of your system like? Is it capable of revealing the difference that the Kimber might make?
