i dont have barrel jacks, but i havent had a problem with monster bass cables. i had mine for about 4 years before i took it in and got a replacement 2 weeks ago. that thing took abuse (like people knocking your bass off the stand while its plugged in and it falls directly on the jack, and i doubt any cable can take too much of that regardless of brand, which is why i keep people away from my stuff, especially the bad kids in the church. lol)
i got a guitar cable, because they didnt have the same size in the bass cable. when i leave my bass at church i use a cheap cable during the week because i dont bring my stuff (somebody stole my other monster cable that i left in the church) but the cheap cable didnt feel loose after using the monster cable.
50 bucks for that monster was kinda a lot, but those Dr. Souls are a bit of change. (cause im an honest guy, but the people that steal cables arent worried about prices. lol)
