I wonder if your idea of holographic has some relation to refinement. I owned the SP501's and say they were more refined and can get you deeper into the music (YMMV) than the Cornwalls (owned those too).
Another thing to maybe consider is- I prefer a narrow baffle speaker to wider baffle typically. I've always thought the narrow gave a more layered stage than the more powerful and maybe dynamic throw of wide baffle.
Finally, also take a look at Devore Super Nines (can be a bit too lively for some) and something from Verity (more of that laid back refinement that I could relate to with the Fyne's
Finally, finally the Fynes don't seem to hold redale as well as some other brands, so if you are going to bounce around a bit consider that too.
