NAD 7140
Brand: NAD
The NAD 7140 is a high-end integrated amplifier that was produced by the Canadian audio company NAD (New Acoustic Design) in the late 1970s and early 1980s. It is considered a classic in the audiophile community due to its high-quality components, innovative design, and excellent sound reproduction capabilities.Some of the key features of the NAD 7140 include:- Fully balanced signal path, which allows for the prevention of negative effects of ground loops and common-mode noise.- Feedback circuitry that is claimed to be virtually unnoticeable, resulting in a natural, uncolored sound.- Switchable tone controls and dynamic loudness controls that allow for greater flexibility in adjusting sound characteristics.- A high-voltage, low-current power supply design that provides impressive dynamics and low noise.- An output stage that uses 120 watts per channel in stereo mode and can produce up to 240 watts in mono mode.The NAD 7140 was also notable for its use of advanced, space-saving internal components, such as surface-mount technology and toroidal power transformers. This allowed for a smaller, more compact design while still maintaining high levels of performance.Overall, the NAD 7140 represents a pinnacle in integrated amplifier design and continues to be sought after by audiophiles today, thanks to its exceptional sound quality and innovative features.
