But any ongoing feedback and experiences any actual owner have, good or bad, is always most welcome so please post guys as, and when, you can.
My bad, I apologize for not expanding on my previous comments, having been an altitude owner for quite some time.
On the question of remapping, let's consider an extreme situation. Imagine you have 2 speakers, a left and a right, and they are placed 40 degrees apart. Can you imagine a "remapping" procedure that would virtually place them 60 degrees apart? No? Maybe doing some crazy phase stuff that makes them sound like they are 60 degrees apart? Would any sensible music lover do this? Would anyone believe it?
Ok so maybe too few speakers in this example. Let's add two rear speakers. Does that help? Hmmmm. I can't imagine that, can you? Add a center then. How on Earth could adding a center speaker help "remap" the left and right speaker to the perfect stereo image of 60 degrees?
And how does this remapping work anyway? Is there some model of the 3D soundfield that you can apply a 3D transformation to, like in 3D graphics, some 4x4 matrix transformation? Or maybe something simpler like assuming all the sources are on a sphere, and then mixing channels together in some interpolation scheme to mix them together somehow, with the bias given for the speaker that is closer? This isn't magic, ultimately there has to be some mathematical formula, some transformation of the channels that... mixes them together in some way as to effect a transformation. And that is the problem for me. The transformation has to mix channels.
Anyway.... the way I see it (and hear it) is that remapping may be interesting in a room with lots and lots of identical speakers arrayed in a much more regular spacing scheme in 3D space. But for me, it does not work. Based on what I hear, in my room. It doesn't work for me. I don't have lots and lots of identical speakers, I have 9.7.8. Even my ceilings are not identical, because the front pair are so close to the screen, that I chose something more directional than the others. My L and R are VERY wide, for home theatre. I used to have them at normal positions, but changed them to make them sound good to me, in my theatre, based on 2 channel music. My Lc and Rc now bisect the angle between the L and R, and they sound fabulous in Atmos tracks, you can really hear the objects moving across the screen in my very wide 25' room smoothly and with extreme precision. They are not the exact speaker as the L/R even though they share some same drivers. But do I want Lc and Rc to have some L and R in them too? Because the ideal speaker position is perfectly between them. So now I have a "fat" L and a "fat" R channel... Aw heck, why not some C as well? For me, in my room, it sounds better with remapping off. But this is why the Altitude is so amazing, you can choose what is best for your application.
And finally, the sceptic in me will make one observation that may irritate some: remapping makes use of all those zillions of speakers and amplification you spent an arm and a leg acquiring. So there is definitely an incentive (and especially from the guy who sold you all those nice high margin expensive stuff) to want everything to work awesomely at the same time. For me, I have found the real beauty of the Altitude thanks to the training Curt gave me: multiple presets. I can use the Lc/Rc as my L/R.... or I can use the L/R. I can use either pair as my 2 channel speakers, and I decide to use them as pure full-range, or with subs.... I can set up my subs as 7 separate subs, or I can group them in larger groups, or I can even specify which sub works with which speaker in any weighting I like, all in different presets. I can use any four of the 8 ceilings for the bed channels (or DTS:X), depending on how I am using the room. I can turn the surrounds off completely, and turn my ceilings into a height plus surround, for the times I have a full bar with 50 people in my room and don't want to have a surround speaker blaring in my ear. And... for the Atmos tracks, I can have all of the speakers working simultaneously. The power of the Altitude, and its 30 presets. Thirty presets. That's a lot of flexibility.
I'm so very close with the construction of my room (which some of you saw when just the front treatment was done), and will be posting photos and diagrams soon, together with the calibration measurements.
