I am very sorry but i have to disagree The sounds inside the Cockpit are exceptional and in high quality. Also the startup and idle sounds are ok. But the cruise sounds are not. To me, and i know it is a subjective isue and i know it is also affected by what sound equipment i use. BUT ....... In midflight trimmed on cruise speed and altitude... the engine dos not sound like it is running smooth... I still hear some stutter and coughs... she just dosn't sound healthy to me. If i listen closely i would be able to count the revolutions. And there is another problem but i guess that can't be fixed due to x-plane limitations: The doppler effect or better words, phase shifting, i get when both engines runing. Just my feel.
