The problem with buying a receiver and using it as a preamp is the fact I'm paying for something I'm never going to use, and all of those amps take up room. I want a slim stream lined preamp that I don't have to take out a mortgage to own.
I'll repeat, it's the economies of scale.
As for those, two words come to mind, rip off. Companies that want to charge a small fortune to have the luxury of a decal on the front panel are showing exactly how greedy they can be. I mean 7500 bucks.....really? Is this thing going to churn out reliable lottery numbers on a constant basis to make up for it's ridiculous price tag? And if they make a product like this that no one in their right mind would buy, why not make one that actually has a option of selling?
Oh and that Denon model is something that would definitely grind my gears if I had to move it for a friend.
There are actually quite a few owners of those here at Audioholics. Hey, they own really nice stuff. They already took care of nice speakers, and most whatever else. There was even a sticky in the amps forum just for the AVP, which Gene also uses IIRC. Found it, has about 300 posts.
Oh yeah, just to get Audyssey Pro capability, it pretty much has to be a dedicated pre/pro, perhaps outside of the Denon 5308, IIRC.

Shock, are you familiar with ARC? How about Gennum? Even bandphan, who is probably the biggest proponent of using display vp rather than audio processors would tell you this unit is the tops.
Like I said, sure you might get less value, but if you have disposable income, and want the best . . .
There are explanations of how the chipsets are superior just in the D2v over the AVM50.
Whatever. You want to go tell them they got ripped off, be my guest.
