Dude i think you got a sweet rig.
You might have to add some room treatments, etc, to get it to sound as good as at the dealers place.
I dont really claim to be an audiophile, more of a Toy-guy, i like expencive toys and i like learnign everything about them.
Like you, i would insist on installing everything myself, for guys like us, that is half the fun! :)
It boils down to this. Do you like your rig?
I will be the first to say this will put ANY cineplex to shame, even in a room that is less than optimal.
I disagree with the BOSE comment though.
I like to think that my ears are developing nicely, i dont have the 20years experience in this hobby as many, but any half-deaf moron could listen to your rig, then a bose rig, and think his hearing suddenly got worse.
every now and then an audiophile will make a comment that all that wonderful gear is wasted on less-than-golden ears. The way i see it, just because you and me might not be able to tell the subtleist of changes like some people can, does NOT mean that we cannot appreciate the wonderful sounds being created, and it definatly does not mean that we cannot tell the difference between your rig, a bose acraptimass system, and a clock radio.
Enjoy your system man!
Someday maybe i will haave something as nice as that.
Good luck on getting everything set up. It can be a very time consuming process, but at least a system like that sounds incredible even if it is not calibrated totally yet.
Just look at it like this, IT ONLY GETS BETTER FROM HERE.
