Thank's for your response.
I wonder if the price of the yamaha is justificated for her power of 85 w. Idon't need of this power beacause the elara are 50w and the onkyo deliver 44w, it's enough for me. What the interest me is the sonor quality and not the power. This différence of price justify the sonor quality ?
The marantz pm5004 is also an option but he seems more dark for the sound and the soudstage is the worse but he have a very good review
The review of the yamaha tell that is little bit more brilliant with good soudstage
The review of the onkyo is also very good with the best soudstage of this 3 amplifier but the bass seems worse than the marantz. I don't need the dac of the onkyo because I have a fiio k3
All of this amplifier are good but différents, that's why the choice is very difficult. My taste for the sound are a large soudstage with good medium and tone. I like the precision but not the brilliance, fast bass with power
The onkyo seems answer better for my tastes but i'm afraid that the bass are small and that the amplifier is too brilliant
your reviews will help me to make a decision for the choice of the amplifier
For the triangle elara, I have a very good price, that's why I have decided to take them
