I would say, yes, the Moreplay is superior in pretty much every way to FPIII. I don't have a lot of issue switching between a Moreplay and a BeePre2 aside from that lovely weight that the BeePre adds. In terms of clarity and natural sound I think the Moreplay is very close, much closer than the FPIII. I would say it is most likely due to the fact that both Moreplay and BeePre2 are single gain stage designs without the added cathode follower impedance compensation of the FP.
