Pioneer has announced their newest flagship digital AV receiver, the 9.1 channel, 140-watt Elite SC-57. It uses the most powerful amplifier of any multi-channel A/V receiver on the market. And yes, it runs Airplay.
The SC-57 uses proprietary D3 digital amplifier technology to drive nine channels at 140 watts each, simultaneously. The amount of powered supplied to each channel of traditional analog amps drops precipitously as more channels are connected. The SC-57 loses virtually none, meaning that you can listen to HD multi-channel Dolby soundtracks as ear-shatteringly loudly as you like. What's more, the amp uses fewer parts (causing less electrical leakage and ringing), a more direct signal path (for faster response times), and an advanced 3600 thermal dissipation circuit board (what? shit gets hot in there) to minimize sound distortion.
Oh, did I mention it runs Airplay? Because it does. The SC-57 wirelessly streams your entire iTunes library and, if you don't use Apple, also features DLNA certified 1.5 streaming via an Ethernet connection. It even connects with Bluetooth to stream content from Androids and Blackberries.
One the video side, the SC-57 uses Marvell Qdeo™ processing technology to not only convert analog video signals to HDMI but also scales video signals up to 1080p/24fps. It will even optimize the video signal depending on what kind of TV you have—Plasma, LCD, Front Projection, whatevs.
