I know this is very, very subjective but let me tell you why I am asking.
I have ordered new speakers and amps (and processor) to move from 7.X.4 to 9.X.6. Given some of
's comments, I am wondering if I might get almost identical performance by keeping the Datasat and making my "wides" discrete by giving up the discrete rears (and making them "copies" of the sides) and give up the top center speakers and make them "copies" of the either the top front or or top rear speakers.
As I have stated elsewhere, the immersion I get now with my RS20i is phenomenal and I truly have trouble believing that the addition of these 4 speakers is going to take me to audio nirvana.
I might be more convinced I was making a true upgrade in immersion if I was going to, for example, 20.X.8 but that is not in the cards
I look forward to your comments.
PS. I have no intention of not moving ahead with the Trinnov but am very curious as to what I will end up with when all is said and done.
I guess let me rephrase what I said. We are actually building a theater in my brother's new design so we are literally "doing it all over again" and I have some opinions of how we are going to deploy our money.
a) i am good with the high channel counts, just not convinced at cineramax's extreme expenditure for channels and amps compared to cheaper options like DIYSG speakers where possible. Just because we have an Altitude does not automatically mean that we can't save on speakers with DIY options if they are very good.
b) I am not that impressed yet with the immersion of many movies but I think they might get better at it is time goes on. I wasn't suggesting not bothering with the channel counts.
Here are the channels that I think are most useful in order of effect:
2 Stereo mains
2 side surrounds (the ones directly to the left and right)
4 ceiling speakers
2 rear side surrounds (these are obviously more important without atmos but with atmos I think the ceiling makes a bigger effect)
6 more ceiling speakers and 2 more behind-the-screen speakers
2 surround wide speakers (i think the benefit of these depends on the specific content and also the type of mains you have). I thought these were much more useful when DTS had its 11 channel matrix mode. With atmos, the ceiling speakers and whatnot have so much more going on that the wides become less noticeable to me).
2 rear wall speakers (just because the channels are available)
1 subwoofer output (the subs otherwise being managed by a behringer ultradrive or minidsp with programming of PEQ derived from andyC's MSO process software or simply set the delays of the subs manually based on MLP.
3-4 subwoofers for maximizing possibilities for MSO optimization - one of these could be behind MLP for near field effect
1 mid bass module per seat in order to get a great tactile pressure wave in near field
We are looking at aiming the side wall surrounds at the farthest away seat so that nearby seats are getting off-axis response which is not as loud. This is to prevent the distraction of sitting too close to surrounds.
I still think the altitude and its optimizer are otherwise great at getting all the speakers to EQ cohesively for similar freq response but I would imagine you get a lot of that effect with a datasat too. I don't know enough about the datasat to comment on comparisons.
As far as audio nirvana goes, I have 19 discreet channels now and I like it a lot. I haven't tried any less channels since I got all my ceiling height speakers at the same time. In our new build we are using all the channels of the trinnov altitude 24 and doing an AT screen (mine is roll down with center speaker below)
We are considering the entire speaker package from DIYSG (titans, volts, and others). we almost finished building a pair of titans and we are going to test them out and then proceed based on our review of them.
I find the
