On the original post, i have a Proteus up and running and its a lovely thing for sure. Compared to my old orpheus it adds a whole load more speed, bite, articulation, slam and dynamics. The treble seems more extended, more real with greater air and the leading edge of bass in particular is much better with just better timing and speed all round. The proteus still has the Orpheus's wonderful unforced sense of naturallness and its still a refined and highly musical non-ostentatious sound, but the soft round politeness has gone and you just feel a fair bit closer to the music, the real thing.
