my system conisists of b&w 685's, an arcam fmj cd17, rega brio3 amp, with atacma nexus 6 stands, and chord carnival silverscreen speaker cable and qed interconnect. i remember my dealer telling me that if i was to ever think about upgrading my kit he reccomended maybe upgrading the brio3. basically i'm very happy with the performance i get from my system but i'm intrigued to find out how if in the future i did decide to upgrade what would give me massive improvements in quality? would for example the kandy k2 be a sensible upgrade for my system? im basically happy with the arcam and the 685's so i dont plan on upgrading those.
