Out of interest, did Yamaha ever upgrade their NS10's to a newer model and if so, was the newer model superior?
Interestingly, to this day, the finest hi-fi speakers I've personally heard remain this ungodly huge pair of 7 foot tall Quad electro-static speakers. They were only 4 inches deep, but they were about 2.5 ft wide and 7ft tall and each speaker had at it's base this remarkable valve driven dedicated power amp. (Apparently electrostatic speakers require much amperage I'm told due to the huge surface area involved...) The guy who owned them said they were very old - as in from the 60's I think.
Has anyone here any opinions on electrostatic speakers?
