Hit and Miss

I've ordered a lot of these from Thomann and I always find they are hit and miss, some buzz in certain areas of the room, some buzz no matter what, some work perfectly. They're so cheap for 10M you can't really go wrong, just wish they were shielded a little better, however I have recorded full band songs with just these cables (9 track drums at the largest point). It's a risk, but a cheap one, would I buy again? Probably not, I'd probably go for the next step up personally. (Maybe Stagg brand cables?)
