The DSP IC in the AV10 is a much improved one even as they went from having 2 of the previous IC to now just 1. The main reason they upgraded to this IC seems obvious, they expected the new series, AV10, 20, and the Cinema 50 through 30 Marantz AVRs, and the corresponding Denon AVRs to do not only Audyssey, but also Dirac Live Bass Control and the latest ART (active room treatment). They also have to allow for users who would in fact use the maximum number of channels, and that would be a whopping
19 on channel count. That would surely use a lot more processing power such as MIPs than the 11 to 15 channel (including the subs) processors that are common just a few years ago.
Since you wouldn't be using room correction, the DSP in your unit would be in the overkill territory and should run a little cooler than others who use it to it's fullest.
Not really in this aspect, the D+M AVRs starting from the AVR-X3800H through Cinema 30 at $4,800 list price ( use the same DSP IC, so it's a matter of software to make them as good in Atoms, Auro 3D, and upmixing that
@dlaloum alluded to.
So, the lowest entry cost could be found at under $1,000 when the X3800H is on sale at some outlets, or the Cinema 50 in Europe in the EU countries and the far East.
Of course for those like you, who won't ever use AVRs, cost of entry is indeed much higher, at $8,000, though the upcoming AV30 will close that gap for sure.
For
some "purist", perhaps including those who believe in their golden ears and would like to consider consolidating their 2 channel setups to just one, the AV10, or the AV20, along with the Anthem AVM90 would still be the go to option, as they are among the very few AVP/AVCs that has ESS's reference class DAC IC that others such as Monolith, Emotiva, and Yamaha (might change if they ever come up with the anticipated CX-A5300) don't seem to bother.
