I added one to my Panamax, Pioneer receiver and subwoofer. Can definitely hear a sound quality difference from my set up as a hole. These cables are giant in diameter compared to the tiny cables that are provided with equipment. Quality of the cable is everything you would expect from Audioquest.

I have always doubted that a power cable would make a difference in what you hear coming from your speakers. I finally gave it a try and much to my surprise there is indeed a change in what I hear . A big improvement in bass response is what I hear and what another person noted, who knew not of the cord being installed. Maybe it's not "Snake oil".

If you are buying a home theater speaker set up make sure you carve out some money in your budget for quality cabling. Originally was going to buy def techs and get 5 of these for receiver, sub, towers, and center but ended up going with the nicest Klipsch had to offer on a sweet deal and just getting two, one for sub and one for receiver because the Klipsch don't use (or need) the built in bass radiators like the def techs have. My advice is to buy your system and get great audioquest cabling and average rocketfish or monster cabling and compare. Then if you don't notice a difference then return the expensive audioquest stuff and throw the rocketfish in the trash and get average audioquest cabling. Mostly because I believe that you are still wrong if you say you didn't notice a difference and the audioquest will perform better long-term anyway. Buy nice cables for a similar reason you buy quality tires for your car (it's the only part of your car that actually touches the road). Your audio spends more time and distance in the cables than anywhere else.

Birthday present to myself as I'm slowly rebuilding system lost in divorce. For now using it for my Marantz SR6014. Did notice a drop in the noise floor. Will know more as rest of system improves

The craftsmanship is stunning. The weight alone makes you wow...when your taking it out of the box. Huge Audioquest fan. Have entire setup is with vodka cables . Worth every penny
