I Have The Same Doubt. Some People Say That Onkyo Is Better Because It's Sound Is "warm". Some People Say That Yamaha's Sound Is "too Bright". But Some Other People Say That Onkyo's Sound Is "opaque" And Other People Say That Yamaha's Sound Is "very Natural", So I Don´t Know What To Believe. I Heard Them Both And I Think Both Sound Pretty Cool. I Don't Know, I´m Very Confused.
