I have a Marantz PM16, Nice solid amplifier. Love to get some measurements. A German audio magazine did some on it an compared it to the Accuphase competition...which it crushed. But it's mid 1990 so not really SOTA anymore haha.
Still think Accuphase makes some pretty gear.
The PM14/5/6/7 series is my all-time vintage Japanese favourite. I adore the curved cases and build quality... they are timeless and up till 2-3 years back, undervalued. Prices now are much higher than when I bought and sold my PM17.
