Edit: I was being silly earlier and originally suggested an Emotiva pre-amp with Dirac Live. Using Dirac to correct a bunch of Bose dipoles gave me some amusement, like putting a humidifier and a dehumidifier into the same room to battle it out Steven Wright style.
But it appears the Bose system uses high level inputs into the bass module for its satellites, but not as a passthrough? The satellites connect to the bass module via RCA. How... odd.
Anyway, to answer the question posed by the article, just get a
refurb Denon from Accessories4less. Doesn't really matter which. Get whichever one has the features you like.

On the other hand, we wouldn’t suggest buying a high end AVR for the sake of additional power or qualitative advantages unless you actually plan on replacing your Bose speaker system with something of higher quality.
It should be noted that "higher quality" does not necessarily mean more expensive, or even
as expensive. There are better speakers to be had costing less than the Bose.
