Have had this cable for 5 years now, and i think its paired perfectly for my tube microphone!
I own various brands of microphone cable but normally use Evolution cable with Neutrik connectors which costs nearly twice (i believe) so was a little unsure of how long this cable would last with these connectors. But surprisingly, they have lasted through a good few years of gigging and the cable is still in great shape and is being used.
SQ wise, to be honest i think its great, i've used it on many recordings with my Avantone CV12 and U87 and it's sounded great.
My only criticism about this cable is that, it doesn't feel as solid as my other cables, it feels soft and bendy compared to my other cables, that just feel thicker. But as said before, it has lasted me 5 years and is still working so i can't really complain.
