MCINTOSH MA6700 Integrated amplifier test

We tested the McIntosh Ma 6700 amplifier in the cinema room of one of the nicely furnished apartments of a modern condominium in the 3rd district of Budapest. The room has adequate acoustics, soft, finely woven, gray Silent soundproof carpet, acoustic curtains, sound-absorbing and diffuse panels have successfully eliminated reflections and standing waves.

McIntosh MA6700

McIntosh in the United States, recognized since 1949 as a manufacturer of audio products. This brand, which can be traced back to a long time, is characterized by reliability, premium quality and clear sound. In terms of appearance, the MA6700 has undergone some innovation over previous models. The polished black glass plate has been given 12 coats of varnish, the characteristic green and blue lights of the display make it clear which brand we are dealing with, while the dot-matrix display gives the device a more modern look. This high-performance High-End amplifier combines a combination of DAC, preamplifier, power amplifier system and phono input. The power of the two-channel device is 200 watts per channel, the frequency travel is 10 Hz-100 kHz, and the weight is 34.1 kg. The speaker impedance is 2, 4 or 8 Ohms. The 11 inputs of the preamplifier and the 3 digital connectors support audio signals up to 32 bits / 192 kHz.

With 2 dedicated phono inputs (MM, MC) it is also possible to listen to vinyl records. McIntosh also has USB, coaxial and optical outputs. Thanks to the Home Theater Pass Through function, it can be seamlessly integrated into home theater systems. Autoformer output transformers ensure that speakers receive 200 watts of power regardless of their impedance and also improve sound. Power Guard, ie power amplifier stage protection, prevents overdriving. The High Drive headphone amplifier optimizes the sound for all headphone types. The MA6700 can also be expanded with an AM / FM radio tuner module. It is also possible to control the treble and bass, of course. At first glance, the Japanese-made modern remote does not fit at all with the classic-looking amplifier, but it is simple and easy to operate.

We have listened

We started testing the sound of the amplifier with movies. We flew back to 1999, when two world-famous films hit theaters worldwide. The excellent Kevin Spacey and Mena Suvari played great in the American Beauty  drama film. The MA 6700 amplifier naturally, cleanly, airily conveyed the sometimes dramatic, sometimes comic atmosphere. It produced a real, lifelike effect. The dialogues were clear. Pierce Brosnan excelled in the role of Agent 007 in the 1999 James Bond film. The world is Not Enough titled film is full of humor and action, and the amp’s performance this time has left nothing to be desired. We got a very balanced sound, dynamic bass and a spacious stage image. We jumped 20 years ahead of time and put the action movie Rambo 5 – Last Blood, released in 2019, into the DVD player.

Sylvester Stallone, like McIntosh, is a legendary and no longer a young actor, but in a way that belied his old age, he fought against the cruel criminals of the Mexican man and drug cartel in this cinema. We couldn’t complain about the amplifier in this case either, the intense bass penetrated our guts, the excitement was maintained by the excellent sound.


The first element of listening to music was Antonio Vivaldi’s fantastic work, Storm. Since the amplifier was also equipped with a phono input, we listened to the wonderful work on a vinyl record. We had a really impressive experience, the instruments rang separately, each frequency sounded flawless. The Mannheim Philharmonic then performed the music for the classic film The Godfather. We can only comment positively about the MA6700, it made me feel so realistic that sometimes it seemed like the band was just in front of us, the sounds came towards us with complete clarity and impeccable dynamics. We also sounded a fresh hit this year with the help of the amplifier. Mamacita, the current song from the Black Eyed Peas band. The McIntosh amp has also successfully coped with the modern music world, experiencing rich detail, demanding sound and definite deep sounds.

Is it worth buying a McIntosh amplifier?

In our opinion, yes ! The American company continues to value good quality and sophisticated sound. This is also evident in this model. The treble and bass can be fine-tuned and precisely adjusted, and the developers have also equipped the amplifier with High Drive, paying attention to the smallest details, which optimizes the sound of these headphones. As a critique, we would mention that the device is unfortunately not capable of digital upscaling, which many may miss. Other than that, it’s worth the price of the MA6700. We rate it 4.5 out of 5 points.
