AudioQuest2 m Black Lab RCA Cable Black - Audio Cable RCA Copper 2 m

I bought this cable after buying a new subwoofer for my home theatre system and finding I had the annoying ground loop hum issue. Apparently this was because with the newer, better sub, it was now picking up the problem that had probably been there all along. Either way, it was incredibly annoying to have this low level hum going on all the time. I had tried all the usual things to stop it and even bought a Ground Loop Isolator remover thing (complete waste of time and money). Getting rather desperate to sort this I rang up KEF who make the sub and asked them, they recommended looking at the Audioquest cables as they have a ground wire that runs with the cable, alloying you to earth the sub to the amp. (By the way, the photo doesn't show it properly, but there is about 6-8 inches of wire for the ground, the pic only shows an inch or so but you do have more room to find a fixing point, I even managed to make it stretch to the ground plug on my amp. For the speaker side you just need to find a screw on the back of the amp to attached it to.)The reason for this rather long explanation is that having googled everywhere for a solution to this and finding nothing, this cable perfectly solved the issue. Although if you talk to Audioquest, as I did, they won't totally guarantee it will solve it, they said in almost all cases it will. I can't recommend them and this cable highly enough as now my lovely new sub works perfectly and it's all down to this cable. Ground Loop Hum is a huge problem if you get it and for home audio or home theatre systems this has proven to be the only solution and I wanted other people to know how they can fix it too. The cables aren't cheap, they aren't that expensive either, but if you've spent hundreds of pounds on an amp and speakers, a few pounds more on the cables to make them work properly seems a justifiable expense.I hope this review helps other people find a solution to the ground loop hum problem as it has me, and I'm delighted.

I tried other grounding devices in an effort to stop the common subwoofer hum/drone that was really doing my head in & nothing worked. But this has fixed my issue & I am chuffed to bits. If all else fails for you, try this cable. Or just buy this cable in the first place. No more annoying sub hum = one happy customer.

Great quality and totally eliminated my sub hum.

I had a hum coming from my KEF Kube-2 subwoofer when connected to my Denon AV Receiver. This cable, when plugged in was still giving the hum until I connected the two pieces to the screws on the sub and receiver. No hum at all now. Great job.

I was looking for a sub cable and was recommended this particular one as it had a grounding cable which helps to limit/stop potential 'hum'. I guess for an beginner in audio this makes the mind field decision making a little easier.Yes its double the price of others but with this feature it makes it a more attractive to people wanting to limit unwanted noise in the signal path.

Nice cable, subwoofer specific, just what was looking for, with that separate earth connection to help eliminate earth loops (only connect at one side, normally the amp, to break the loop - can get complicated though). Tightened up the bass as well.

Bought as part of upgrading my TV surround sound system over Xmas was recommended to me .Up to this point performing well no feed back humm. Good length as well for money .

Good quality cable
