I need an AV receiver with preouts. I want to use the preout to drive the front channels through my main sound system. My main speakers are Magneplanars. These are very large speakers that are supposed to be almost inpossible to match to a center speaker. I plan to use the Phantom option in order not to have to use a center speaker. The AV receiver will do the decoding and drive the subwoofer and the rear channels. For such a setup, would the Denon 2802 bring significant advantages over the 1802? Any alternative AV receiver suggestion will be appreciated. Replacing my main system with the AV receiver is not an option.
