Yamaha’s YPAO calibration system is tasked with dialing in your speakers and making acoustical adjustments. The entire process only takes a minute or two and unlike Audyssey, you only need to place the mic in one position. The results were solid, although it mistakingly labeled my fronts as large.
Streaming music to the RX-581 via one of its multitude of streaming options is a simple process. In the past, Bluetooth on Yamaha receivers could be a little difficult to get up running. With the 581 I had no such issues. After I pressed the Bluetooth button on the remote it was just a matter of pairing the amp with my phone. AirPlay and internet streaming worked equally well.”
