Thank-you, Irek. The marantz av8805 is a pre-pro (or is the av8805 really just an avr as you say?). If I do go with the marantz av8805, then two marantz mm8077s would provide the amplify grunt. just wondering what speakers (atmos ceiling, fronts, sides, rears, centre) I should consider (or avoid) if i go down the marantz av8805 and mm8077 x 2 road. I am seeking a multichannel surround sound (immersive audio) ... rather than two-channel. thanks for your contribution! being a newbie (and a retired old man), i am looking to the wisdom of the sna family to help me along my journey. ta.
