This thread is beginning to sound like one about power output watts..
Suffice it to say that implementation
is really the crucial factor, having the silicon DSP horsepower/headroom and memory are required as well..
If one is comparing processor speed they will know/understand the importance of memory interface, the DA710 having a 32 bit vs. the 16 bit (708) those can now understand its significance. The processor engine may be capable of doing a certain # of operations..
If its memory interface is overloaded
, gridlock time (like the 405 freeway @ 5:00PM) and the system slows down..
Or like trying to run Vista or Windows 7 on a 1 Gig Intel processor..
Another point is the # of DSPs, more is not
Remember quality vs. quanitity, and if one does a search they will find a number of threads noting the significant latency issue
within the Onkyo AVRs. Since the digital audio stream is routed through 3 different DSPs....
Basic reason 3 DSPs are used is cost...
The stepdown DSP (708) is significantly cheaper
than a higher horsepower DSP (710)..
Now, lets get back to the primary issue...
Audyssey vs. Dolby....
Hopefully others will post their comments, even better a test lab will run an audible comparison with one of the new Onkyo platforms.....
Assuming their implementations are correct...
Just my $0.015..
