From reading comments here I would not go anywhere near Levinson stuff. Well let me tell you put-downers and haters that I own an ML23.5 and it is a great amp, really great. There is no bling, no 'show' just a plain looking form follows function amp.
I bet some of you mouthing off have never heard his early stuff. ML was taken over by the giant Harman group and are producing components designed not by Levinson himself but by other audio engineers and marketed under the ML name yet nobody seems to find fault with that. ???
