Now that's very cool.
The engineer deserves serious respect.![]()
I edited and corrected "that part" of my writing which now should be read as "But in 2019, I have confirmed it.....". It was just before I started my multichannel fully active exploration.
Of course, he added "But it (make it in fully active) would be all your responsibility! Of course any warranty and even any possible repair service (as whole SP system at YAMAHA factory) with charge will disappear for you!!", and I accepted that.
I carefully incorporate protection capacitors for my treasure midrange-squawker, tweeter, super-tweeter, and also always perform careful ignition/startup sequences and shutdown sequences (ref. here).
Very fortunately, since so many units of NS-1000 and NS-1000M have been sold in Japan, I still can rather easily find and purchase used but in good shape (or even excellently refurbished) SP drivers on several web sites for my NS-1000, if needed.
