I just received my forza audioworks hybrid cables for my 846s and a hybrid lod cable for my Walkman to my RSA Shadow amp. I did quite a bit of A-B testing between the stock cable and the forza one. I wanted to do my damndest to make sure I wasn't experiencing a placebo effect. I am sure there is a difference between cables despite what others say. Now, that being said, it wasn't a night and day difference. What I experience with the hybrid cables is a bit wider soundstage, mids that sounds more detailed, and smoother/better blended at the same time, and highs that have a bit better presentation, and no loss of the wonderful bass these produce. I will say there was no discernable change in bass with the cable switch, but I will never go back to the stock cable. As a bonus, I find this cable much more comfortable than the stock one. If this new Sony dap coming out lives up to the claimed battery life, I do believe I've found my end state for portable audio.
