Marantz PM-11S3 Reference Integrated Amplifier

Massive and Musical: Overbuilt Marantz PM-11S3 Reference Integrated Amplifier Delivers Even the Most Delicate Passages with Ease

HDAMs, Buffer Stages, Excellent MM/MC Phonostage, Headphone Amp, Huge Toroidal Transformer, Ability to Drive Any Loudspeaker: Marantz PM-11S3 Reference Integrated Amp Has It All

Marantz's PM-11S3 Reference Series integrated amplifier affords that rare “wow” factor sought after by every discerning music lover. Think back to the first time you heard a system that forever altered what you thought possible to aurally experience, feel, and imagine. Again and again. That's the PM-11S3. Overbuilt with proprietary Hyper Dynamic Amplifier Modules, buffer stages, a fully discrete constant current feedback MM/MC phonostage, and more, this reference component is the sonic truth. So go ahead and spoil yourself. You deserve it. Particularly when it's backed by our 100% Money-Back Guarantee.  

Overbuilt to Impress
Enclosed in a new black chassis, PM-11S3 is the most impressive-sounding and overbuilt integrated amplifier in its class. The power supply, that critical stage that provides operating voltages for every circuitry stage, features a massive toroidal transformer newly configured for minimum mechanical vibration. Completely covered by an aluminum case, and mounted to the chassis on its own 10mm-thick aluminum base, this multiple-secondary device alone weighs 14.5 pounds. Another power supply design element is a choke input that uses a large capacitor to eliminate high-frequency noise. Schottky barrier diodes in the rectifier section provide high instantaneous current capability and quicker response than conventional circuit elements.

HDAMs in Newest SA3 Configuration, Outstanding Phonostage
PM-11S3's preamplifier section features fully balanced circuitry with liberal applications of Marantz's HDAM (Hyper Dynamic Amplifier Module) in their newest SA3 configuration. Sonically, the SA3 analog outputs assure smooth stage-to-stage signal transitions and help provide the realism so prized by music lovers and audiophiles. Each input includes a separate HDAM-SA3 buffer stage that virtually eliminates unwanted interactions between source and amplifier. And, of course, the XLR input's buffer is a balanced HDAM configuration. The phono input, ready for both MM and MC phono cartridges, boasts full constant current feedback topology implemented with discrete device. It minimizes the sonic discontinuity often observed with lower-quality equalization circuits. 

Able to Double Down Power Into Low Impedance
The final preamplifier stage includes a high-precision digital volume control. Augmented by more HDAM devices, it provides easily repeatable gain settings as well as faultless transition from preamp to power amp stages. On the amplifier side, PM-11S3 evidences the same level of careful consideration. Signal traces, the copper "roads" that carry current, are far wider than convention dictates. Configured as two "semi-monoblocks" that share only a common chassis, power cord, and transformer, each amplifier channel draws on the MA-9s2's minimalist two-stage design in which a voltage amplifier determines overall gain and then feeds a current stage that provides the force needed to drive the loudspeakers of your choice. The end result? An integrated amplifier comfortable with virtually any loudspeaker. With the ability to "double down" power into low impedance, PM-11S3 often surpasses the speaker control capability of so-called "muscle amps."

Superb Foundation, Elegant Looks
A 5mm-thick aluminum plate tops the rigid copper-plated chassis. Its dual-layer bottom provides a firm foundation for all internal components. Two sets of WBT speaker terminals and front-panel A/B speaker switching add a rare level of convenience. You can also configure a pair of these remarkable components to bi-amp your favorite speakers. And F.C.B.S., Marantz's proprietary Floating Control Bus System, synchronizes for up to three PM-11S3s for multichannel applications. Front-panel cosmetics are as advanced as the circuitry behind them. Indirect blue LEDs display status with a décor-friendly sophisticated elegance. The display is a low-noise LCD that exacts no performance penalty as it keeps you informed about PM-11S3's operation.
