Are future improvements in Amp/PreAmps slowing to a crawl?
Think most missed Nelsons real point-  {largely solved on a practical level} amplifiers have existed for decades that can run a loudspeaker reliably affordably and efficiently.  
Why are tweeters so high off of the ground in many tower speakers...
With your loudspeaker at that height the accuton tweeter is off axis pretty much bouncing its energy over a seated listeners head that is sub optimal design. Design appears to be modeled after the old Wilson watt puppy setup and that I have had ex...
