@topfinadv, Please read this review of the NSMT Model 100, it plays to your main criterion of soundstage;  https://6moons.com/audioreview_articles/nsmt/     Manufacturer website;  https://nsmt-loudspeakers.com/

How about these?  I think quite a few people really love them.  They are possibly the most impressive speaker that I’ve ever heard.

Could try OB’s. PureAudioProject Quintets, Trios, Jump in at any size. Upgradable without loss of investment, efficient, Just ask VPI, Whammerdyne, and more that use them to demo their own products. Says a lot. Once heard, not easily forgotten. 

@bbenzaquen6343- I’ve found both Kimber Selects (KS-1130 & 1030) and Synergistic Research (Tesla Apex & Analogue Tricon), to pass whatever determines accurate ambience retrieval, without hindrance.      I’ve no doubt; their later iterations would be even better, in some ways.

I too used the ML Prodigy. They sound better bi-amped with an active crossover. Better yet are the Quad 2905’s. I have owned two pairs of 2905’s and one pair of 2805’s for ten years or more, and am just experiencing my first failures. One panel has gone (out of 32) and one high voltage transformer.

If you don’t use them like sonic bludgeons they seem to work fine - at least, mine do. Once you’ve lived with ESL’s, I don’t think there is any going back. One highly respected member here owns MBL’s and he opined that they were better than anything but ESL’s.

If you like the ESL sound, stay with it, I say.
