There is a company in Germany that is producing ARC 050 & 102 speakers again, it's on PFM under the Nytech thread.
There is a Nytech company that services and produces Nytech stuff. TBH I didn't think much of that demo of the new stuff, they were at a show (maybe Manchester) I went to.
The vintage stuff is a bit corse, but it boogies in a way a lot of new transistor stuff doesn't.
The Nytech CA252 and CA302 are Nytech's Naim Nait 1 & 2, too much for too little money that is a hard act to follow.
