Simple amplifier with ICEPower 125ASX2

Hi, reading the forum, I recently finished an amplifier with ICEPower 125ASX2 module, which is giving me great satisfaction.
As a simple self-builder, without technical training, I share this project with you, hoping it will be useful to someone novice but who wants a complete and well-sounding amplifier. Everyone can improve it.
I don't speak English well, so I apologize for my language. I'll ask my friend Google Translate for help.
Have a nice Sunday.

Hi, thank you for the work you have done on the ICEPower modules for audio DIYers. I have seen your pages many times and have enjoyed reading about your projects.
At first I thought about using an OPA1656 as a preamp, then I found a Muses01 for a nice price from a French dealer and I wanted to give myself this "gift". I did well, because in my system there is no match with the NE5532. But I left open the possibility of doing some op-amp rolling with the OPA1656, which I'd like to hear.
I saw on your blog that you made a comparison between 1656 and 1642. When you can say a few words about the listening results I would like to know your opinion ...
