The M33 has a high-quality MM Phono Input that rivals specialized outboard units. Accurate RIAA equalization, a clever phase cancelling infrasonic filter, and a huge overload margin combine to bring out the best in LPs. Furthermore, headphone enthusiasts will delight at the sound of the discrete headphone amplifier, which is able to drive even planar and high impedance studio phones. With high voltage and low output impedance, headphones will sound their best. For those who wish to enjoy their headphones but not be tethered to a cable, the integrated Bluetooth AptX-HD module makes it simple to possible to enjoy wireless headphones as well.
With the employment of the new Purifi Eigentakt Hybrid Digital amplifier technology, the M33 follows NAD’s long-standing tradition in identifying and developing cutting-edge amplification technology. With a minimum of 200W per channel on tap, the result is lifelike performance, exemplified by ultra-low distortion and noise.
