I would love to talk to you about this. I also am extremely disappointed in the audio after the upgrade to MCU2 so much I want my MCU1 back! I also have been spending the last 2 weeks trying to dial it in. (Music now hurts my ears with settings I have used in every stereo I have had in the last 30 years) I will read your post and DM you if I need further help.So in this thread, there have been many questions about the audio coming from MCU1 to MCU2. After my upgrade over a month ago, I was initially disappointed with the sound of MCU2. After a month of frustration in trying to tune the system but never getting it quite right, I decided to spend a day on an audio project and use a little science instead of just my ear. I mapped out the frequency response of the MCU2 audio and adjusted the limited EQ the software allows to obtain a much better sound.
