Opinions on Shunyata power cables w/Velodyne subs

Anyone tried a Shunyata,Nordost or similar power cable on a Velodyne subwoofer? I would like to know what your results were. Were the results worth the costs?
I did, but honestly it was hard to notice a difference... the very faint hum was reduced though. I have Shunyata cords on all my other equipment and I do really like them.
Right church - wrong pew. Try the subwoofer power cords from Synergistic Research on your velo sub. I have had very good results with them - less bloat, more precise pitch and seemingly "faster" bass. Good Luck!
