What can come after Apogee Divas ?

I had started a similar thread in 2002 when I moved from Europe to the US and thought I would have to leave my Apogee Divas behind that give me so much pleasure for years (with active cross-over, run with 2 Krell KSA-300S Stereo amplifiers). But I managed to bring them over and so continued to enjoy the huge sound stage and clarity of these ribbon speakers. I listen both to classical 2-channel music, but also run a 10-foot screen 5.1 movie system and multichannel SACD with these speakers as 'mains' (and Duettas in the back). Now they show some signs of 'aging' with a slight rattlling sound when brass intruments are reproduced at higher volumes.
Where should I go from here if I cannot find help with their recalibration/repair? SoundLab U1? JM Lab Utopia Nova? Quad ESL-989? Dynaudio Confidence C4 or Evidence temptation? Martin Logan Prodigy? Wilson Audio MAXX or Watt/Puppy? Thiel CS5i or 7.2? Wegg3 Lunare 1? Krell LAT-1? What is likely to give a similar performance to Divas in a large media room and is more 'future proof'?
