I don't want to be rude despite I feel angry and disappointed. I've only a vague feeling to be on board like before in my career. Indeed, I used this real aircraft nearly at a full time during 3 years in the cabin and sometimes in the cockpit for take offs and cruise. I barely feel and hear this typical CFM sound (with more bass and "stereo sound" as it's 4 of them compared with the A320) despite the 2nd update made it a little better. Even this one from LVFR make me more happy but its aircraft is just bad.
You're right. This is subjective. In addition, sound isn't my job ans words can't express a feeling entirely. If I'm the only one to complain I'll ask for a refund and it'll be fine, too.
