Conclusion: I've spent a lot of time with the Marantz PM-11S1 and I can say it's one of the most beautiful pieces of gear I've come across. The measured power this integrated amplifier exhibits told us that Marantz plays fast and loose with its stated power specs - but in the consumer's favor. Its styling is unique to Marantz and really makes a statement in your reference system that says this is a serious piece of audio equipment.
Pros: Best-in-Class Performance, Elegant look and feel, Balanced inputs, Superb chassis and component shielding, Hi-end binding posts, Stereo and Bi-amp mode, Preamp outputs for expandability, Far exceeds its power spec
Cons: Not inexpensive, No DACs - analogue inputs only, Remote not backlit
