MARANTZ - SM-11S1 REFERENCE STEREO POWER AMP
The New Marantz SM-11s1 Reference Power Amp Will Blow You Away... and that's a Guarantee! Its time for an Upgrade!
The Marantz SM-11s1 competes with designs that cost twice, even three times as much. At the heart of the SM-11s1 is a new revolutionary Marantz design: the HDAM-SA3. The SM-11s1 employs no less than 34 of them! To say the toroidal transformer in this muscular amp is big is an understatement. The amp weighs in at 60 pounds! All circuits inside the SM-11s1 are fully-shielded, with a chassis completely lined with copper for absolute isolation. Exceptional parts quality is used through the entire signal path.
Custom Marantz block capacitors and resistors, Blue Star film caps, gold-plated inputs, and German-made WBT binding posts were all chosen for their sonic benefit. Rated at 110 watts per channel into 8 ohms and 220 w/ch into 4 Ohms, we haven’t found a speaker that can’t be driven by this exemplary amplifier.
The Marantz SM-11s1 makes listening to any style of music an absolute pleasure. Audition this amplifier in your home, and you will become engulfed in sound quality like you have never before experienced.
“Considering the SM-11s1’s superb build-quality inside and out, its fit’n’finish, its fully balanced architecture, the fact that it can be bridged for use as a monoblock – and of course, its dazzling sound – its difficult to imagine any company [producing] such an exceptional design for $4000. The SM-11s1 is one of those ‘get it while you can’ products that comes along all too infrequently!”
Michal Fremer, Stereophile, May 2008
“Overall, the Marantz SM-11s1 Reference offered a very clean bill of health on the test bench. It was a pleasure to measure an amplifier so competently designed.”
John Atkinson, Stereophile, May 2008
