When planning to purchase an AV receiver, a future user is faced with numerous questions that cannot always be dealt with without a specialist. We will try to answer many of these questions in a review of one of the receivers - Marantz STEREO 70s. During the review, we evaluated the technical characteristics and features of the device. 7 out of 10 - this is the estimate that we consider fair. The release of this receiver took place in 2023. The model from Marantz can process 2.2-channel sound.
