As a former Diva owner, I've considered the "What's next" question for some time. If I were buying today and had the appropriate room, the only real (apples-to-apples) candidate would be the big Magnapan, the MG-20 or whatever the current iteration is. For someone used to the "huge ribbon" sound, NO electrostat will do the job, and no dynamic speaker is fast enough. Used Divas are an alternative, but then there's the question how to repair 'em.
Best of luck!
