The Arcam AVR550 AV Receiver is in the middle of Arcam’s Full Metal Jacket (FMJ) line. It shares many features with Arcam’s flagship model, the AVR850, but for a lower price tag. The AVR550 sports a full complement of the latest surround decoding abilities including Dolby Atmos and DTS:X. It also sports audiophile quality DACs and some surprisingly good power amplifiers.
