I think if my old Onkyo was next to the Yammie it would be like the show of Dean Martin and Jerry Lewis.
I think it has to be the processor; the receiver is not working properly, it can't recognize some surround formats (DTS and the internal DSP'S) initially, but it does it after a while. When i hear music trough a digital connection, every time at the beginning of a CD, it misses like the first half second of the first track. When i repeat it, it doesn't happen again until i change the CD.
The most noticeable faliure is that "optimizer" appears on the display when i'm using the graphic equalizer and it shouldn't do that. It should appear only if i have engaged the parametric equalizer.
I read the manual like a dozen times and it says nothing about how to "re-initialize" the receiver.
