I am currently a 2 channel person and need advice in converting to HT. I have read many of the discussions on this BB and have not come accross one that discusses my delima. My current system is Rotel, Marantz, and Klipsch KLF-30s. I listen to Classic Rock and like anything that is mixed well. My problem is that I like the system I have but can not find a HT system (pre-amp) that has true 2 channel capabilities. I like using seperates because I can upgrade one piece at the time. Does anyone have any suggestions for pre-amp and matching speakers for my KLF-30s?
