I just recently got a mini lab for my subwoofer which is amplified. The amp would run hot if I was playing at volume for an extended playing time causing it to shut down. It looks like the power cable is helping it to run cooler. I got the mini because I had a Lab p.c. for my amp & REL subwoofers have a circut which tries to mimic the sound of your main amp so for synergy I got the mini. It is a well made cable but I can't state it made a difference in the sound. At this pricepoint you have EEL reference which I have in my system & you could also pick up a used Syn. Research p.c. The big Lab cable is a bargain especially for powering amps. I wish I could give you more information but they do have a free 30 day home trial for you if you are in doubt. Larry
