Trial and error ! We checked what the Marantz 7706 knows!

The basic condition for perfect acoustics is the acoustic treatment of the given room. On-site and online acoustic measurements can be used to determine the appropriate type, quantity and ideal location of sound-absorbing and diffuse elements. If you really want to achieve perfect sound in your cinema room or sound recording / mixing studio, take care of the acoustic treatment of the walls, ceiling, and glass or floor surfaces. The Marantz processor was tested in a cinema room with excellent acoustics. We only recommended soundproof curtains in front of the windows. Special, high-density materials prevent unpleasant reflections, dampen noise from outside, and with these curtains, up to 99% darkening can be achieved, which is an important aspect for cinemas.

 We’re starting a rehearsal with the music film Rocketman, released in 2019, about Elton John’s life. Marantz produced a detailed, spacious and clear sound, and the vocals and dialogues were understandable. The processor provided a noise-free and lifelike experience, combined with the Marantz MM8077 external amplifier and JBL speakers.

In 2009, a 3D-based sci-fi film, Avatar, directed by James Cameron, was released in cinemas and soon became a worldwide success. We experienced perfect sounds, fantastic effects and precision. We, too, could feel like members of the blue avatar people while watching the movie.

We continued testing with the movie Rise of the Planet of the Apes. Each sound in the 2011 film sounded impeccable, and the excitement of the scenes was further enhanced by the real-world sound.

We selected vinyl records for listening to music. We first listened to Mozart’s Symphony No. 39, interpreted by the Berlin Philharmonic. Past and modern technologies were perfectly attuned to each other, and the wonderful music on the turntable sounded flawless. The music surrounded us, it seemed as if the band was playing right in front of our eyes and ears.

The iconic legend Frank Sinatra’s 1969 album came into our hands. While listening to the song My Way, we were immersed in the performance of the deep, humming singer and the rhythms of the soft, delicate music.


The Marantz AV7706 preamp can be a worthy member of a home theater system, paired with the right external amplifier and monitors. Made by manufacturers from quality parts, through a careful and precise development process. Intense depths, optimal and clear high and mid ranges characterize this fantastic device. Marantz has convinced us once again that their development engineers really understand their business. We strongly recommend the AV7706 to anyone who values excellent sound and premium quality. If we were to score, we would give a maximum of 5 points out of 5 to this processor.
