Funny you should ask! Kidding, my buddy recently compared a few digital cables. We heard differences for sure. Hugh difference, well nope. Slight differences in overall dimension, clarity, smoothness, etc. The higher priced digital cable won out but not at two and a half the price difference. It also did not have the clarity of the cheaper cable. My other friend couId hear the differences in our other friends system but not that much in his system so system dependent? have stated many times in the past, swap out a few resistors and you will probably hear bigger differences. I have a selector switch in my preamp so I can change resistors to go with the recording on the fly!
Happy Listening.
