Sndsrtaud,
IT can vary, but I use DNM Reson ICs throughout my system. I like these for their flexibility, cost effectiveness, coherence and overall clarity. The bass tends towards the leaner side compared to some ICs but is very articulate and full and a nice match to the OHMs.
For a fuller low end, I also like MIT networked ICs. I use the older and less expensive Terminator series ICs. I tend to prefer these more with my monitors.
FOr speaker cables, I have no clear preference. I use industrial grade in wall speaker wire to my f5s which reside in the room adjacent to my gear. The results are very good having tuned everything accordingly.
In my main room where my gear resides, I use more expensive AUdioquest cv6 speaker cables. I have had my 100s and Triangle monitors in there. My Dynaudio monitors are in there currently. The CV6 sounds very open and dynamic in there with all, but the OHMs tend to respond to tweaks the most.
