I am using PNF ICON and MAC Mystics ICs and PNF Symphony speaker cables. I find the ICON throws a huge and deep sound stage with a lovely tonal balance. Smooth, slightly on the warm side (at least compared to silver), open, and airy. However, the presentation is a little too recessed in my system and the airy quality takes away some of the richness I enjoy. The singer is way back there and gets trumped by instrumentals. MACs are very smooth, rich, and luscious sound, but rather compressed presentation. So in the end, PNF from source to preamp and MAC from pre to power amp ended up working superbly for me.
