In the modern home theatre environment, features and connectivity are as important as sound and picture performance. The Pioneer VSX-921 excels in all these areas. It combines four 3D-compliant HDMI inputs with DLNA streaming of HD audio files over a wired network, internet radio and wireless music streaming via AirPlay. Under the bonnet there a total of seven discrete amplifiers with sufficient power to drive the vast majority of home theatre systems. Pioneer’s familiar MCACC room correction regime is included, with the added flexibility of further fine-tuning via a PC application over the network. Last but not least, Pioneer’s new AirJam iPad app offers an interactive way for friends to fill the party with music.
