Glynn, I noted in earlier comments that piano on the X5s, and I am sure the X3s, is just spectacular. Unlike geerock, I have never noted any "grainy" sound from the X5s even right out of the box. This weekend I hope my last set of AntiCables arrive. Then I will have completely transitioned system to AntiCables. So far, I am finding the voices to be more natural and instrument placement more 3 dimensional with these cables. Hoping the final add, the series 5 speaker cables continues the improvement. Previous cables were Audience AU24 SE which are excellent. System sounded spectacular with the Audience cables. Anticables sound is similar to the Audience AU24 SE sound, but with the changes noted here.
