Is there a reason they're going without toroidal power now? It seems that the only way to get it in 2015 would be to go via costly separates (the stunning AV8802 etc).
I absolutely love the sound of my SR8002 and am only looking to upgrade for the sake of 3D and 4K pass-through, network / streaming, Atmos etc.
I believe I wrote a reply to a similar question like in the Denon 7200 thread:
"It's all about cost, and the first thing to give in the current economy is the power section.
Toroidals cost $$, and most consumers won't notice.
It's only a AVR after all, so one cannot expect it to give the same results as a solid power amp.
These days, consumers want all the features but do not want a price increase. So what is compromised is the power section, which is something many consumers do not notice, especially when they look at the specs and see "wow, it has nine channels of 160W per channel".
Not too many reviewers measure the power supply too, and amps change so often, it seems we won't be seeing a proper review of this amp during it's lifetime..
Even so, if it can generate half of it's rated power per channel, that should be enough for most mid-range HT speaker setups. After all most consumers don't run all the channels at the same volume, nor do they run their speakers full-range. Many have one or even two subs to help take the load off the amp."
