I second the notion of which speaker cable is better being dependent on the sonics of your system. I felt the Transparent MM2 Super speaker cables wonderful until I moved into a house with a brighter living room and with my already slightly bright system, I then found the warmer Audioquest Gibraltar better on balance. However, I feel it worth while to note differences between the two speaker cables.
The Audioquest Gibraltar speaker cables added some needed warmth and were slightly more dynamic than the Transparent cables in my new brighter listening room, yet the Transparent MM2 Super speaker cables, although warm and with a nice black background, were not as warm as the Audioquest Gibraltar speaker cables - although the Transparent MM2 Super surpassed the Gibraltars in capturing the beauty and tone of female voices and had more extension in the treble registers. Both cables presented good bass. I needed more warmth, so the Gibraltar on balance won out.
You always get something and loose something. The better cable is the one that blends into your system best for your preferences. I hope the above gives a meaningful reference though for some differences between the two cables.
