Subaruguru: My EMC-1 is the latest "UP" version. Still, I think focus is not the best I've heard. As far as the RCA v balanced connection thing goes. If indeed the RCAs are wired with cheap hook-up wire as you say, it does not speak well of EC considering the price of the machine IMO. Your statement brings another point to mind. Perhaps the differences we attribute to wire are not as significant as we like to think. Why? Well, I heard my EMC-1 through its balanced connections and in the same system (not mine), through its RCA connectors. There certainly was more headroom through the balanced. More punch, which I liked. Perhaps a smidge more direct sounding. Aside from that, I sure wouldn't go crazy looking for a new preamp for my own system to accomdate the EMC-1's balanced topology. Detail, soundstaging, frequency extention, etc.. It was all there through the "cheaply wired" RCAs.
