While the AV8802A and AV8805 look similar, the AV8805 has over 1,900 part changes that are meant to enhance audio quality. These include faster DSPs, new isolation plates between the transformer and chassis to reduce noise and vibration, additional shielding and isolation between the DSPs and the audio PCBs, a new DAC board layout with a shorter signal path for improved jitter reduction, and updated HDAMs (Hyper Dynamic Amplifier Module) with precision-matched discrete devices.
One thing Marantz hasn’t updated is its best-in-class user interface, one that I find to be extremely intuitive and easy on the eyes. When powering up for the first time, you are greeted by a guided setup that walks you through the installation. First, you tell the processor how many components you’re using. Next, you’re instructed to connect the included Audyssey microphone to the unit’s front so that MultiEQ XT32 equalization can work its magic
