To meet the diverse requirements of high current drive and high dynamic power, our patented PowerDrive amplifier circuit will build further on our reputation for amazingly effective power. By adding a second high-voltage rail to our well regulated high-current power supply, we get an "overdrive" that can nearly double the continuous power on a short term dynamic power basis. This is a further development and refinement of our renowned Power Envelope circuit, utilized by NAD in the 80's and 90's. PowerDrive differs from Power Envelope in that it offers greater amplifier stability and low impedance drive capability, resulting in less distortion when driving real speakers with real program material.
SOUND, NOT SPECS
Specs are, by their very nature, just a snapshot of an amplifier or receivers capability. NAD's Full Disclosure Power Rating is an attempt to bring a broader understanding to the power rating issue. But, in the end, it's not ratings you listen to; rather it is music or movies playing through loudspeakers in your listening room. In other words, your own ears will tell you everything you need to know about power. When you listen to the clear and intensely detailed sound of NAD, with its powerful and extended bass, you'll understand why we focus on low impedance drive capability. And when you notice the relaxed and unstressed way an NAD sails through musical and cinematic climaxes, you'll appreciate the engineering behind PowerDrive, with its incredible dynamic power reserves.
