Top critical review
on August 7, 2013
I bought two of these... i'm guessing I didn't see that these came in greater lengths... not sure, but got two and plugged up my subwoofer to my new Pioneer 1023K receiver. I joined the cabels with a RCA coupler that I've used in the past for audio cables. within minutes, the subwoofer just hummed, like there was no tomorrow. I read many reviews and what to do to get rid of the hum. all the ground loop eliminators I found, the reviews were towards auto engine noises etc and none were directed towards home A/V receivers. I read a lot about grounding issues within a house and how it's best to use 1 receptacle opposed to multiple, but then it hit me... the subwoofer box doesn't have a ground pin, so that didn't make sense.
Then an electrical engineer friend asked... if it didn't hum before it could be the receiver but did you try using other cables? sure enough, 'other' older thinner cables work fine. then I tested 1 of the new cables and it was fine, but then the second one - HUUUUUMMMMMMMM!... so one cable is worthless and the other is good... at least for now.
for $5, i'll throw it out or use it to tie something out back. I just ordered a coax 35 footer double shielded and this thing looks like it belongs in the space shuttle and only cost $16... i'm wondering if it's going to be hummm free.
Hope this helps.
gave it 3 stars, because there was no 2.5. for the one that works I guess it's a 5 star rating, but the other one is a zero star, therefore 3 stars!
