The 30.2 XD are a step up in dynamics and scale from an LS3/5a speaker and are world class.
The only caveat is that they might be a bit too smooth sounding with an overly smooth amplifier like a Luman. I demoed them with the new Luxman L 507z and the sound was golden and euphonic and a touch too smooth overall.
Good news is that the sound is still exceptional and can be made to pop simply by removing the grilles. Recommended.
