Sub cable: Syn R. v Tara L v Nord. v A.Metallurgy

I am trying to find a subwoofer cable that helps produce intricate, detailed, fast, and non-boomy bass for a home theater LFE application. The bass should also present an expansive sound stage.

My reference has always been Synergistic active sub cables, which certainly accomplishes the above. I have 4 lfe subs that go into an xlr splitter. The cables leaving the box to the subs are all Synergistic Research.

I now need a 1.5 meter cable that leaves my processor and connects to the splitter. As a more cost-effective alternative for this 1.5 meter cable, has anyone heard or compared the following subwoofer cables:

*Synergistic Research active sub cable vs....
*Tara Labs RSC Sub
*Nordost CinemaFlex Bass-Line
*Audio Metallurgy Ag-0
*Audio Quest Sub-3

Which one will be the best (and likely the most similar to the Synergistic sub cables? If the Synergistic will likely outperform the other sub cables, please let me know.

Thanks
