The sophisticated home cinema deserves audiophile-quality sound to match: NAD’s 2700 THX amplifier achieves just this. It’s a powerful yet refined stereo amplifier conceived especially for sound reproduction in the most critically demanding of home-theatre and hi-fi audio systems. A 150 watts-per-channel design with impressive dynamic power and peak current capability, the 2700 THX combines superb acoustic performance with excellent reliability at an affordable price. Something audiophiles expect from NAD. The 2700 THX was among the first designs in the world to meet LucasArts Entertainment Co.‘s stringent specifications for amplifiers in advanced Home-THX home theatre Home-THX components bring to domestic audio systems performance equivalent to that heard in LucasFilm Ltd licensed commercial THX theatres - that is, the very best in cinema sound. NAD’s 2700 THX achieves performance that is truly state-of-the art, whether employed for audio/visual, or for purely musical sound reproduction. NAD’s Speaker Impedance selector and high-current out-put stage deliver maximum power to loudspeakers of any impedance - high or low, simple or complex. The model 2700 THX will even drive a 2 ohm impedance safely, without current-limiting or distortion.
