Thank you LOTR
In surround sound i meant,those those background sounds from movies which make the movie enjoyable and more realistic ?
Without 765 in picture how good is yamaha 565 alone ? Does this have good surround processing modes which yamaha is famous for ?
If you're talking about Dolby TrueHD and DTS-HD MA from the Blu-ray discs, and decoded by these receivers, these two receivers are equal.
If you're talking about the DSP surround effects, added to the original soundtracks, like Yamaha YPAO, and Onkyo Audyssey, then it's a question of personal taste. Me, I prefer Audyssey.
Yes, the 565 includes few of the good DSP surround modes which Yamaha is famous for.
But everyone has his own opinion about them. At the beginning, it's fun to play with, but you'll soon get bored after a while, like I did with my own Yamaha. I was not using them anymore, or only very rarely with some Jazz & Classical music, but not for very long.
I'm a purist.
