The Quad Electrostats were one of my references back when I jumped in the deep end of hifi yet again back around 2008. I ended up with newer Ohm Walsh speakers that I still have and seemed to hit the mark overall.
More recently , I also added KEF Ls 50 metas and those take detail to the nth degree I’d say as a result of technological innovation baked into those and other newer KEFs. White papers on how they do it are readily available.
