In advance, I've looked at different 5.2 amp, from pioneer to Yamaha, Sony and co. However, the Onkyo scores extremely ergebniss the prize money. 100Watt per channel that is a stunner. On the whole functions I can not go into here, because there are too many. The amplifier detects no problems my TV (Samsung) My Media Player (Asus) My NAS system (Zyxel) It automatically detects the audio signals (stereo, 5.1. (AC3), DD5.1, DTS, and much more.) Clearly whoever a 5.2. Seeks amplifier and does not want to spend more than 300, and wants to have 100Watt per channel Onkyo should buy.
