Bear in mind that there are two major camps with regard to audio quality. One insists that the appropriate digital processing, including room equalization, will provide the best results for both multichannel and stereo systems. The opposing camp prefers using minimal but high quality analog electronics between the source and the speakers. i.e. don't use a middle-of-the road AVR. Both agree that you should spend most of your budget on high quality speakers and that room treatments are extremely important, too.
You'll have to specify a budget to get the most appropriate recommendations.
The Integra 80.3 has replaced the 80.2
Onkyo seems to have gotten a bad rep for reliability in recent years.
The Denon 4311ci seems to be the most cost-effective high-end AVR right now (~$1.5K) Its replacement hasn't been announced yet.
Marantz is expected to announce at least one new pre/pro later this year, perhaps two.
