"Premium" might last longer but unless it's really cheap muck you won't hear any difference in the sound. Don't trust the hype mate.
A number of years ago Richer Sounds mugged me into buying some supposedly high-end phono leads, I later discovered they're not even properly screened.
I make my own now. If you can wait (and are handy with a soldering iron) you can get decent quality components / cable and do the job yourself for a fraction of the cost of ready-made ones AND you know what went into it.
