I cannot exactly talk with the ISO incorporation. But, I did lately buy a new processor; a Marantz AV 8801 and I really like it a lot. The installation was the most convenient of any receiver/processor I have ever possessed. Also, there is a lot of manages as well.
An AV8801 from Marantz as a preamp/processor is the machine of my dream ! Tell us more about it if you don't mind !
