I also am quite pleased with how holographic or 3D my system sounds with the XP-20. However, this was improved by placing the XP-20 and other components in my rack on Vibraplane and Townshend Seismic Sink isolation platforms. The increased isolation allows very subtle ambient cues captured on some recordings to become apparent through the system. I think it has to do with superior needle/groove contact. I don't know what is happening when I put my SS electronics on the isolation platforms, but the sound improves and one area of improvement is imaging and presence.
The XP-20 is very good in my system and I'm sure the XP-30 is even better, though I have not yet heard it.
