I just recently took delivery of a pair of Sierra-2s (having already owned Sierra-1s for some years) and am so far very pleased. I have been wondering whether another speaker cable would serve the speaker better than the 12G Monoprice wire I am currently using. I unfortunately need a 25 foot run and felt that the ultralink bulk cable sold by Ascend is probably not much better than the Mono. I obviously want to avoid the snake oil cables, but I have been wondering whether some entry level cables (Blue Jean Canare 4s11, Audioquest type-4, QED XT40, River Cable Starflex or others) might be a meaningful improvement. I wonder if anyone has some experience with such an upgrade for the Sierra-2s. I am running them with an Acurus DIA-150 integrated amp that runs about 150 per channel into 8 ohms. I look forward to your thoughts.
