Broken AudioQuest Caldera speaker cable ends...

My dog decided to try to play my stereo this morning, and lay down on my AudioQuest Caldera center channel cable, pulling my Martin Logan Theater off it's shelf (it fell five feet and wedged between the broken sheetrock and my tv stand, with damage to two corners of the ML) and snapped the Silver tips off the amplifier end. Does anyone know if I can send this back to AudioQuest for factory replacement (the heat shrink will need to be re-done also) or should I try DIY? It's an $800 cable, and I don't want to make it a $100 cable by not terminating it correctly. I'd rather have spade connectors than the factory banana tips (the spades might have survived the pressure); will I lose signal using spades instead? Any thoughts or direction would be helpful. Thank you. Carl
