Guys,

Appreciate if you can advice the difference between listening in:
1. AUTO/ALC/DIRECT MODE
2. STANDARD MODE

After reading through the manual, I still could not be very sure of the definitions. My understanding for STANDARD MODE is that the avr will try to force source (of any number of channel, including those without surround originally) to surround mode. But I am not sure. Is this right?

My conclusion in listening to both modes is that the STANDARD MODE sounded very thin while pure direct mode sounded much more musical and warm.
I would like to know which mode you all use most often - STANDARD or AUTO/ALC/DIRECT MODE?

Your advice is much appreciated!!
PS: coming from an lx-53. Previously own vsx520 does not seems to have such significant differences between these 2 modes.
