Marantz MA-6
(1984 - 1986)

Rare update to the Ma-5 monoblock, introduced in Japan along the Sc-11 & Sm-11, CD-84 or PM-84 units.
Specs for the Ma-5 and MA-6 are equivalent, though, just as the Class A or AB operation possibility.

Differences lie in the chassis (copper all over), and the possibility to use an MA-6 monoblock as a BTL unit - one MA-6 for each side of the signal phase! The CC/DC input possibility and the GND terminal of the Ma-5 were scrapped, while the flashy LEDS gave way to a cooler encased red LED lighting the front description from above.
The output devices probably changed as well...

It seems the MA-6 wasn't sold in the US but it seems the MA-7 was ; both of them seem fairly identical although there seems to be some differences between the two. "Seems" is the word.
The MA-6/MA-7 were later replaced by the x-rare MA-7A, part of the more clearly affirmed Music Link series. But just as rare.
