Supplying the demands of dynamic and powerful movie soundtracks in a theater using large speakers requires a serious amplifier.  NAD set out to build just that.  Using a mono-block design, each of the 5 amplifiers weights as much as a lot of receivers.  Everything was overbuilt and ready to supply the demands of a serious home cinema.  The S250 uses a massive Holmgren toriodal transformer for a huge reserve of power.  Even the protection circuitry in the amplifier uses multiple stages for safe and dependable operation for years to come. 
This amp is built like a tank and compares to amplifiers selling for double the price.  Don't miss this opportunity. 
This amplifier was lightly used and is in excellent condition.  The satin silver anodizing is stunning to see in person.   
Note:  The power button was off in the photos and will be included with the unit.
