Hi Grimace,
Were the "half a dozen pretty well-regarded speakers" you tried back-to-back in your system, a dealer system or a mix of systems?
I've found that Piano is a great work out for any speaker, though we must remember we are listening to a system rather than just a speaker as Zd542 points out.
Over the years I've made three observations about piano reproduction. First, we tend to underestimate the amount of bass needed to cleanly reproduce low left keys. Recordings with low C can be revealing. Second, since a hammer is hitting a string and that string oscillates it is always revealing to listen to note decay. If your overall system and room has a low noise floor then the overtones seem to sustain for a considerable period. Third, piano and valve amplifiers seem to be a match made in heaven!
