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.
