Need help buying new speaker cable


My Tara Labs Apollo speaker cable broke at the negative terminal end.  I will need to replace them.  What cables would you recommend?  I would like to know what cables out there would be comparable.  I would like to upgrade but they need to be affordable. A local dealer recommended Audioquest Robin Hood’s but they cost $2,000.  I just can’t spend that much money.  I am looking at Audioquest Rocket 88’s for $1,150.  Any ideas?  I would also like to know what the sound difference be compared to my Appolo’s?  I still have a difficult time you can hear a sound difference between one cable and another.

I am not going to delete my post above even if I seem like an atheist in a bible study group! In fact I have been buying and trying wire in my various HiFi systems since the late 70's! Interconnects and speaker wire. My favorites were the Verion Triaxial ICs made by Mitchell Cotter. I had six pairs. For speaker wire I used the Mogami 2477 Blue Neglex coaxial 12 gauge cable (bought a 40 foot piece from my local audio dealer for $40, cut it in half and terminated the ends). 
Remember that all these cable/wire companies want your money and they will say anything within legal boundaries to entice you to open your wallets! Call me suspicious, particularly when I read words like "quantum tunneling", "cryogenic processing", "perfect surface", "oxygen free", "directionality" ...
