I own a Spacedeck and went from a Zyx Fuji to Airy3 with nothing but joy and more joy. From general consenus here, the Spacedeck is not on the same level and holds these cartridges back. But they definitely still shine through on this TT in the areas you mention (particulary acoustic harmonics!).
I don't have direct experience, but you may get most of what I'm hearing from something more modest($), such as Zyx Bloom or Shelter 501?
