here’s nothing like taking a good
product and making it better, and if
anyone should know how to do this
it’s Marantz, because Marantz has
been doing this very successfully for the 61
years it has been in business (the ownership
of the company has changed a few times over
the six decades, but the brand is the same).
The latest product to benefit from a Marantz
‘facelift’ is the long-running PM-11S amplifier
design, now in its third generation (hence the
‘3’ at the end).
What’s changed? One major change
involves useability, because you can now use
the PM-11S3 in conjunction with Marantz’s
Remote App (available for both iOS and
Android) via the Marantz control bus with
Marantz’s new Network player. There’s now
a power-amp direct input, new heavy-duty
copper speaker terminals and, internally, up-
dated versions of Marantz’s Current Feedback
HDAM SA3 modules.
What hasn’t changed? That would be
the triple-stage construction (preamp, dual
power amplifiers, plus phono preamp—MM/
MC), oversized toroidal power transformer,
symmetrical circuit layout, Shottky diodes,
choke power supply filtering and high power
output capability, even into extremely low-
impedance loudspeaker loads. And you’ve
got to love that copper-plated chassis, which
looks absolutely superb…
