Devialet Immersive Theater System

[octaviars]

You're looking at it from a physical point of view (number of speakers to which each channel can/could be mapped) and I was thinking about the encoded channels in a surround bitstream. I guess neither of us is really wrong.

Yes that is a way of looking at it also so as you say none of us are wrong 

Todays imersive sound system is ofcourse different when you can map speakers anyware in the room a friend of mine has a Trinnov Altitude 32 8-8 and that is one impressive pre-amp bit precisely like Devialet they are a bit odd to work with......must be something French
