I don't know the specifics of the JPS design, but i do know that proper impedance characteristics can DRASTICALLY improve the sonics of a system. If JPS is using some type of impedance compensation network on their digital cabling, along with good quality conductors and dielectric, i don't doubt that it is a good sounding cable. I've been using a cable that has those features for several years now and Stereophile ran an article about this very subject about a year or so ago. The fact that any cable can be modified in this manner and improve performance makes it a no-brainer in my book. Why more manufacturers don't use such an approach, i don't know. Sean
