I suppose it depends to a certain extent whether you want your viewing and listening all in the same place or can separate them, and which aspect you value more. Much as I love my v8, if I was mainly interested in home cinema I would probably consider other options. If I was mainly in it for the music, then wanting to keep my M speakers, I'd likely go 818 even though I'd miss Trifield. As I value both aspects roughly equally, what I have now works well for me. Some future MQA passthrough option would be nice though.
