after a number of researched and highly recommended choices that let me down I decided to try out these cables from thomann.
I use these on a daily basis in my studio and often are in use throughout a week not even having the connected items turned off and not once have I had a problem .
the provide perfect clarity and performance and consistently through constant and rigorous use, they look clean and discreet in the studio and are substantial in their build quality .
as far as con's on this item I really am unable to provide any after a considerable amount of use over a long stretch of time they continue to impress and are something I would purchase again in a heartbeat .
