Arcam set out to design a no compromise, reference standard multi-channel power amplifier when they had the Arcam P777 in mind. We believe Arcam have achieved that aim. With seven channels of 150W each, it is an extremely capable and yet subtle design which every high end home cinema would love to have at its heart. Stunning realism with HD movies, concerts and music is possible with the P777 – awkward loudspeaker loads present no problem as it can double its output current as the load halves, due in part to its highly over-specified power supply. All this power would normally product mountains f heat, but with efficient class G circuitry, massive cool running heatsinks and fan assistance if needed, it never even breaks sweat. Each power amplifier board is supplied from its own dedicated transformer windings, so that crosstalk, hum and noise are eliminated. The in-rush current generated by these two huge toroidal transformers would normally present a problem, but Arcam have cleverly incorporated a soft start circuit that slowly ramps up voltage and current at switch on, to eliminate any false tripping of fuses. All control and supervision circuits are housed in their own aluminum cases, to prevent any digital noise from entering the audio path. Naturally, both balanced (XLR) and unbalanced (RCA) inputs are present, as are high quality gold plated loudspeaker binding posts. To hear movies how the director originally intended, the high end AV enthusiast simply must hear this FMJ amp..
