I went from a Clearaudio Virtuoso Wood MM to a Zyz Fuji MC on my Spacedeck. The most obvious differences were microdynamics (or perhaps more delineation of individual dynamics for each instrument or sound?), as well as greater tonal richness and dimensionality to each instrument/sound.
I'm using Lundahl step ups, which sound fine and cost alot less then the Bent Mu's.
